Pad the weapon support in the bed of the truck with cellulose wadding and tape with 2-inch
cloth-backed tape.
3
Pre-position two 30-foot lashings lengthwise across the cargo bed, passing them through
the left and right tie-down rings in the cargo floor.
4
Pre-position two 15-foot lashings widthwise across the cargo bed, passing them through
the front and rear tie-down rings in the cargo floor.

Cut a 15 ½- by 80-inch piece of honeycomb. On one end of the 15 ½- by 80-inch piece,
make a cutout 14-inches down the 80-inch edge and 5 ½-inches on the 15 ½-inch side.
6 Cut a 36- by 80-inch piece of honeycomb. On one end of the 36-by 80-inch piece, make a
14-inch cutout cut on the 80-inch edge and a 25-inch cut out on the 36-inch edge. These
cutouts will fit around the support brace. Place honeycomb on top of the pre-positioned
