Fire Missions
This chapter consists of three sections: parts of a standard fire mission; basic fire
missions, which contains basic digital and manual fire mission procedures; and
special missions, which details specific missions such as registration, illumination,
coordinated illumination, and FPF.
SECTION I. PARTS OF A STANDARD FIRE MISSION
This section discusses the features of basic digitally and manually generated MFCS fire missions. It includes
the sequence of actions and screens used by the MFCS operator during a fire mission, and common actions
performed throughout the operation. This section explains the steps common to all digital and manual fire
missions.
STANDARD FIRE MISSION PROCEDURES
16-1.
The MFCS provides a standard set of steps and screens to view the fire mission data for grid,
polar plot, shift from a known point, and quick fire missions, whether the missions are input manually or
received digitally. From the initial CFF to the EOM, the sequence of actions is standard, although some
steps may be omitted or repeated for all CFF, regardless of the type of equipment supporting the FDC. The
MFCS also uses common actions to process fire missions and transmit commands. Special missions
(registration, illumination, coordinated illumination, and FPF) also use the standard set of screens, as well
as the same common actions.
SEQUENCE OF ACTIONS FROM THE INITIAL CALL FOR FIRE TO
THE END OF MISSION
16-2.
Fire missions are composed of four basic components: the initial CFF, adjustment to the initial
data to move the fire onto the target, an FFE, and an EOM. The sequence can also be stopped at any time
with an EOM from the FC or FO. This sequence is as follows:
(1) The initial fire mission occurs. The initial fire mission can be a new or an established target.
(2) The fire is adjusted onto the target. This may be omitted if the initial impact hits within the
target area or if the mission is an FFE.
(3) The FO or FC calls for an FFE.
(4) An EOM is sent from the FC or FO, and the mission is saved or deleted.

DIGITAL AND MANUAL FIRE MISSION TABS AND SCREENS
16-3.
Figure 16-1 illustrates the format of all View screens. The control button area, displayed to the
right, is used to select the MFCS functions. The tab area, located at the top of the screen, displays the types
of missions available to the user (Manual, New CFF, or a previously saved mission). The working button
area, located at the bottom of the screen, contains buttons to accept, modify, or refuse the data shown in the
working area. The working area can have up to four subareas: the Messages screen, the gun status area, the
Fire Command fields, and the View button areas. The View button area provides the operator with the
means to select different fields for viewing data.
Figure 16-1. Mission Data screen.

COMMON ACTIONS
16-5.
The MFCS operator repeatedly uses commands throughout the fire mission. These commands are
usually performed by selecting a button or responding to a query in a message box. Common actions
include—
z
Acknowledging receipt of the message.
z
Accepting or refusing the mission.
z
Processing or deleting the mission.
z
Selecting the guns to fire the mission.
z
Confirming gun orders.
z
Accepting or modifying data.
ACKNOWLEDGING RECEIPT
16-6.
The operator selects the OpAck button to acknowledge receipt of a message and deactivate the
audio alarm, if it is turned on. The phrase “acknowledge receipt by selecting the OpAck button” is used
throughout the chapter to indicate this action.
RECORDING DATA
16-7.
The operator records data throughout the process to maintain a record and to preserve data should
the MFCS fail. He transcribes data onto DA Form 2399-R or DA Form 2188-R. The phrase “record data”
is used throughout the chapter to indicate this action.
MESSAGE TO THE OBSERVER ACCEPT OR MESSAGE TO THE OBSERVER DENY
16-8.
The MFCS operator selects message to the observer (MTO) Accept to accept the mission and
MTO Deny to refuse the mission. If the operator selects MTO Deny, the Delete button becomes visible
and, when selected, deletes the mission. If there is an error beyond FDC control, the only choice is MTO
Deny. The phrase “select MTO Accept to accept the mission or select MTO Deny to refuse the mission" is
used throughout the chapter to indicate this action.
PROCESS OR DELETE
16-9.
The operator may select Process to continue with the mission or Delete to stop the mission. The
terms “process” and “delete” are used throughout the chapter to indicate this action.
SELECTING THE GUNS TO FIRE THE MISSION
16-10. The software preselects guns for the mission; they are checked in the Sel box in Gun Select. The
operator can modify these selections by checking or removing the checkmark in the Sel box beside any
OpRdy gun. The operator may also select all or none of the guns listed by selecting All or None. The
phrase “select guns” is used throughout the chapter to indicate this action.
ACCEPTING OR MODIFYING DATA
16-11. If required, the operator adjusts the mission data. To undo any changes, he selects Undo Changes,
and the data fields display the original data. If any changes were made, he selects Use All to accept all of
the changes. If no changes were made, he selects Use All. The phrase “modify data if necessary” is used
throughout the chapter to indicate this action.

SECTION II. BASIC FIRE MISSIONS
This section details how the MFCS is used to conduct digital and manual fire missions using each method of
target location. It also explains how the MFCS records RPs, targets, and known points.
BASIC DIGITAL MISSIONS
16-12. New basic fire missions are received digitally from the FC or FO. The FC or FO identifies the
target's location using grid coordinates, polar plots, or shifts from a known point. Once a mission has been
fired, it can be saved and designated as a target or known point.
16-13. The following screen shots provide an example of a new digital CFF using the grid method of
target location. The process is the same when using the polar plot or shift from a known point method of
target location. Except for the initial CFF screen, the adjustment of fires, FFE, and previously fired
missions are conducted in the same manner.
RECEIPT OF A FIRE MISSION
16-14. Upon receipt of a fire mission, the Missions button is highlighted and, if enabled, the audio alarm
sounds. The operator selects the Missions button, and the New CFF tab appears (Figure 16-2). The
operator can select MTO Deny to deny the mission or Process to display the Mission Data screen.

MANUAL MISSIONS
16-26. During manual fire missions, the FDC receives the data from the FC or FO by radio or some other
non-digital means. On the Manual Mission screen, the operator selects the type of mission (grid, polar plot,
shift from a known point, or quick fire) and enters the required data into the displayed fields. Once the type
of mission and the initial firing data are entered, a manual fire mission is processed in the same manner as a
digital mission, except for commands from the FO. The example outlined in the screenshots uses a grid
mission to explain the steps involved in a manual mission.
NOTE: For a manual fire mission, commands from the FO have to be entered into the MFCS.
After the data have been entered, the operator processes missions using the sequence of screens
described in paragraphs 16-13 to 16-25.
MANUAL CALL FOR FIRE
16-27. The operator selects the Missions button and the Manual tab. The Manual CFF screen (Figure 16-

MISSION DATA SCREEN
16-49. The Mission Data screen (Figure 16-21) presents mission data and a new target number. It allows
the operator to review mission data and make any necessary adjustments. Guns for the mission are
preselected, but the operator can modify the selection by checking the box beside any OpRdy gun. In a
one-gun illumination mission, when deselecting one gun and selecting another, the ammunition and sheaf
selections in the Fire Command fields automatically change to an HE round and linear sheaf. The operator
must reselect the correct shell, and the sheaf automatically defaults to “1 Gun IL.” If necessary, the
operator makes adjustments to the mission data. For example, he may change the MOC from WR to AMC.
Then, he selects the Use All button to display the Solution screen.
NOTE: Two-gun lateral sheaves are recommended for area targets, and two-gun illumination
sheaves are recommended for point targets. The standard coverage for

16-53. Before sending gun orders or at any time during the mission, the operator can check the safety
data by selecting the Safety Data button. This screen (Figure 16-23) includes the location and altitude of
burst, and the impact point of the canister. The Plot button is available to review the plot at any time during
the mission.

MISSION STATUS SCREEN
16-55. When the operator sends gun orders, the Mission Status screen (Figure 16-25) appears, and the
words “Gun Orders Sent” are displayed in the Views section. The Fire button is displayed because the
MOC was AMC. When the guns send “Ready,” the Ready button is shaded, and the operator can select the
Fire button when required or when ordered by the FO or FC. The mission is monitored from this screen.
The operator updates the status of the guns (Ready, Shot, Rounds Complete, and Abort) from this screen,
and the MFCS automatically sends this information to the FC or FO.

SUBSEQUENT MESSAGES ADJUST FIRE
16-56. When the operator selects the Msgs button, the Messages screen (Figure 16-26) appears, and the
operator waits for subsequent messages from the FO or FC. Upon receipt of an adjust fire message, data
are recorded, and the operator acknowledges receipt. The operator has a choice to Process or Delete the
adjustment. When Process is selected, the Mission Data screen is displayed. The operator makes the
necessary adjustments to the data and selects the Solution or Use All button.
Figure 16-26. Messages screen.
16-57. To complete the illumination mission, the operator continues to make adjustments to the
illumination until he receives an EOM message or another mission, such as coordinated illumination, from
the FO or FC.
16-58. The FC or FO contacts the FDC to “Mark Illumination,” and the operator records the mark time.
The MFCS operator also sends a plain text message to the illumination gun to inform the squad leader that
the illumination has been marked and that he needs to maintain a minimum of three to five rounds with the
current data. The mission stays open in case corrections are needed later.
COORDINATED ILLUMINATION MISSION
16-59. Illumination fires are often coordinated with HE fires to expose and kill or suppress the enemy.
This mission is essentially two separate fire missions, with the operator alternating between the
illumination and HE fire missions by clicking the tabs for each mission. The type of round and fuze
combination used with illumination depends on the type of target. For example, HE is used for troops in
open areas, and WP used for a suspected POL point. There are three parts to a coordinated illumination
mission:
z
Adjustment of the illumination and ordering its fire during the HE adjustment and FFE.
z
The adjustment of the HE.
z
The coordination of illumination and HE fires.

ADJUSTMENT AND FIRING OF THE ILLUMINATION
16-60. The adjustment and firing of the illumination mission is similar to that of the digital fire mission.
Illumination is fired and, if necessary, adjusted throughout the coordinated illumination mission. Once the
illumination is adjusted, the operator receives a subsequent adjust message for FFE for the illumination gun
mission and processes it without adjustments using the Mission Status screen. During the HE adjustment
and FFE, the operator receives subsequent messages (from the FO) to fire illumination in coordination with
the HE. To do this, he alternates between the Illumination Mission tab and the HE Mission tab. After the
illumination is adjusted, the method of command for both fires is changed from WR to AMC.
HIGH-EXPLOSIVE ADJUSTMENT
16-61. In illumination missions, the procedures associated with HE adjustment are similar those that
occur during the adjustment phase of a basic digital mission.
(1) Upon receipt of a fire mission, the Missions button is highlighted. The operator selects the
Missions button, and a New CFF tab appears.
NOTE: Because of present software limitations, the CFF message states that this is an
illumination mission, but it also serves for a coordinated illumination mission.
The operator decides whether to deny or process the mission. If the mission is acceptable, he
records the data and selects Process.
(2) The screen now displays the mission data. The operator processes the mission in the same way
and uses the same screens as he would for a regular HE adjustment, except for the MOC. The
MOC is changed from WR to AMC. After making any other adjustments to the data, he selects
Use All, and the Solution screen appears.
(3) The Solution screen shows the gun orders, the guns selected, and errors and warnings. This
screen allows the operator to review the gun status and to change the gun selection based on
errors and warnings received. From this screen, the operator can select MTO Deny
(if
necessary) or MTO Accept, and send gun orders.
(4) Before sending the gun orders, the operator checks the safety data by selecting the Safety Data
button (he can also check the Plot screen). He reviews and records the safety data and selects the
Solution button to return to the Solution screen.
(5) When ready, the operator selects Send Gun Orders and confirms the order. A Send Status box
showing the destination and status now appears.
(6) The Mission Status screen appears, displaying the words “Gun Orders Sent.” The mission is
monitored from this screen. Gun status is checked off as completed, and messages are
automatically sent to the FO or FC. When the adjusting HE gun sends “Ready,” the operator
begins coordinating the illumination and HE fires.
(7) A Subsequent Adjust message is received for the illumination gun mission. The operator
processes the mission without adjustment and selects the Fire button.
(8) The operator waits for the appropriate mark time and clicks the Fire button for the HE mission.
(9) The operator continues to perform the steps above until the Subsequent Adjust FFE or EOM
message is received.
FIRE FOR EFFECT
16-62. Upon receipt of the Subsequent Adjust FFE message, the operator records the data and can either
process or delete the mission. Selecting Process displays the Mission Data screen.
(1) The operator changes the method of command from WR to AMC. When complete, he selects
the Use All or Solution button.
(2) At the Solution screen, the operator reviews and records data. He also checks the Safety Data
and Plot screens. Then, he selects the Solution button to return to the Solution screen. When
satisfied, the operator selects Send Gun Orders and confirms the order. Then, he waits for all
guns to report a “Ready” status.

(3) A Subsequent Adjust message is received for the illumination gun mission. The operator
processes the mission without adjustment and selects the Fire button.
(4) The operator waits for the splash signal and the appropriate mark time. He then selects Fire for
the HE mission.
(5) When each gun reports "Rounds Complete," a checkmark appears in the Rnds Complt box. The
operator then responds to any subsequent messages.
(6) When the EOM message is received, the HE mission can be saved as a target. The operator
discards or saves the mission using the procedures described in paragraphs 16-24 and 16-25. He
can save it manually by following the instructions in paragraphs 16-36 to 16-39.
(7) The operator also ends the illumination mission but does not save it.
CALL FOR FIRE FROM FIRE SUPPORT ELEMENT OR FORWARD OBSERVER
ILLUMINATION AND COORDINATED ILLUMINATION POLAR PLOT MISSION
16-63. These missions are conducted the same way as grid missions, but the New CFF screen has the
Polar method checked.
CALL FOR FIRE FROM FIRE SUPPORT ELEMENT OR FORWARD OBSERVER—ILLUMINATION
AND COORDINATED ILLUMINATION SHIFT FROM A KNOWN POINT MISSION
16-64. These missions are conducted the same way as grid missions, but the New CFF screen has the
Shift method checked. The FO automatically converts a shift from a known point mission to a grid mission
before the FDC receives it. The location is not as precise as a regular grid mission since the last digits of
the direction, the lateral displacement distance, and the range displacement distance are automatically
changed to zero.
MANUAL ILLUMINATION AND COORDINATED ILLUMINATION MISSIONS
16-65. Procedures for a manual mission are similar to those for a digital mission. The only differences
are that the operator must manually initiate the CFF, manually select Subs Adj whenever a subsequent
adjust is warranted, and manually click EOM to end the mission.
NOTE: See paragraphs 16-13 through 16-25 for details on manual missions.
FINAL PROTECTIVE FIRES
16-66. An FPF is an immediately available, prearranged barrier of fire designed to impede enemy
movement across defensive lines or areas. The MFCS can store up to three FPFs at a time. If an active
mission is in progress and an FPF order is received, the FPF mission has the higher priority.
NOTE: This paragraph uses a grid mission to illustrate the process of receiving, adjusting,
saving, and firing an FPF. Missions using the polar plot or shift from a known point method to
locate the FPF are conducted the same way.

MISSION DATA SCREEN
16-68. The operator selects Process and the FPF button; the screen displays a New FPF Target Number
tab and the Mission Data screen (Figure 16-28). Guns for the mission are preselected by the software, but
can be modified by the operator. If necessary, the operator makes adjustments to the mission data. In
Figure 16-28, the MOF is ADJ, and the MOA is danger close; these fields are auto-filled and read-only.
The MOC is AMC. The sheaf defaults to Linear, but the preferred sheaf for an FPF is Special. For a special
sheaf, the system allows the operator to enter the length, width, and attitude. Based on the attitude of the
target, the operator ensures that the adjusting gun is the one closest to the FPF. Since the FPF mission is
also danger close, the preferred fuze to adjust is Delay. In the ADJ section, the operator chooses DLY for
Fuze, if available. The Use box is checked automatically when a registration correction is available. If a
registration correction is available, the operator has the option to use Reg Correction. If the operator
decides not to use it, he selects the checkmark in the Use box to deselect it. If no changes are made, he
selects the Solution button or selects Use All to display the Solution screen.
