## Description Of Load

9-1. Two M119A2, 105-millimeter howitzers are rigged on a 20-foot type V platform with an accompanying load of 63 boxes of ammunition and 21 cans of fuzes (when required).  This load requires four G-11 cargo parachutes.

## Preparing Platform

9-2. Prepare a 20-foot, type V airdrop platform as described in Figure 9-1.
- **Inspecting platform**.  Inspect, or assemble and inspect, the platform as outlined in TM 10-1670-
268-20&P/TO 13C7-52-22.
Note.  If the platform must be assembled, install the suspension bracket assemblies when assembling the platform.  See Figure 9-1 for the location of the suspension bracket assemblies.


Note.  Measurements given in the chapter are from the front edge of the platform, NOT from the front edge of the nose bumper.

## Step:

1. Inspect, or assemble and inspect a 20-foot Type V platform as outlined in TM 10-1670-
268-20&P/TO 13C7-52-22.
2. Install a suspension bracket assembly to each platform side rail using holes 6, 7, and 8.
Face the flat part of the link to the front of the rail.
3. Install a tandem link to each platform side rail using holes 1, 2, and 3. 4. Install a suspension bracket assembly to each platform side rail using holes 33, 34, and
35. Face the flat part of the link to the front of the rail.
5. Install a clevis on bushings 1 (triple), 2, 3, and 4 of each of the front tandem links.
6. Install a clevis on bushings 1, 2, 3, and 4 of each of the right front suspension bracket
assemblies.
7. Install a clevis on bushings 1 (triple), 2, 3, and 4 of each of the left front suspension bracket
assemblies.
8. Install a clevis on bushing 2 of each second suspension bracket assembly. 9. Starting at the front of right platform side rail, install clevises on the bushing bolted on
holes 9, 11, 13, 15, 18, 20, 21, 23, 24, 26, 27, 30, 37, 38, 39, and 40.
10. Starting at the front of left platform side rail, install clevises on the bushing bolted on holes
11, 12, 16, 18, 19, 20, 21, 22, 23, 24, 26, 27, 30, 31, 38, 39, and 40.

## Stowing Accompanying Equipment

12-4. If the accompanying equipment (paragraph 12-1) is to be dropped, stow it as shown in Figure 12-6.



Stow the equipment in such a way that it will be no higher than honeycomb stacks 4 and 5.

1
Lay a 15-foot tiedown strap on the platform across stacks 4 and 5 with the ends of the
strap on top of the stacks.
2
Fit the accompanying equipment in the space between the stacks on top of the strap.  If
lumber is included in the accompanying equipment, stow it on its edge against stacks 4 and 5 as shown.
3
Bind the equipment with the 15-foot tiedown strap, a D-ring and a load binder.
4
Pass the free end of a 15-foot tiedown strap through clevis 4A and a second strap through clevis 4.  Run each strap through it's own D-ring and pull the straps taut (not shown).
5
Run these straps up over honeycomb stacks 4 and 5, and secure the straps together with
two D-rings and a load binder.

## Preparing Howitzer

12-5. Prepare the howitzer as described below.


Insure the metal breechblock support bracket is available.  A previously airdropped howitzer should have it's own breechblock support bracket.  If a bracket is not available for the howitzer, use the specifications given in Figure 12-7 to construct one.  The breechblock support is constructed of steel.

Use 2- by 6-inch and 2- by 10-inch pieces of lumber to build the wooden support blocks for the gun tube according to Figure 12-8.

Prepare the radio, power distribution unit and batteries as shown in Figure 12-9.

Prepare the gun tube as shown in Figure 12-10.

Lash the gun tube as shown in Figure 12-11.

Secure the baseplate, hoses and aiming stakes as shown in Figure 12-12.

Prepare the manifold and quadrant mounts as shown in Figure 12-13.

Secure the carrying case and spades as shown in Figure 12-14.

Secure the collimator as shown in Figure 12-15.
Stow the equipment in such a way that it will be no higher than honeycomb stacks 4 and 5.

Notes.  1.  All measurements are given in inches.
2.  This drawing is not drawn to scale.
3.  The support is made to allow for metal shims to be inserted to ensure a snug fit under
      the breechblock.
The breechblock support bracket must be fitted to the individual howitzer.


Notes.  1.  All measurements are given in inches. 2.  This drawing is not drawn to scale.

1
Cut four 2- by 10- by 57-inch pieces of lumber.  Nail the four pieces of lumber together with
20d nails.
2
Make an arch-like cutout in three 2- by10- by 12-inch pieces of lumber.  The arch is based
on a 5-inch radius centered 2 5/8- inches above the top of the wood and 6- inches from
either side. Nail the pieces together and to a 2- by 6- by 12-inch piece of lumber with 20d
nails.
3
Make an arch-like cutout in three 2- by 10- by 12-inch pieces of lumber.  The arch is based
on a 5-inch radius centered 2 1/2- inches above the top of the wood and 6- inches from
either side.  Nail the pieces together and to a 2- 6-by 12-inch piece of lumber with 20d nails.
1
Place honeycomb on top of the radio inside the box.  Pad the front of the radio with
cellulose wadding and secure the box latches.
Notes.  1.  Located on both left and right trails are three boxes containing the power supply
                  distribution unit, radio, and batteries. Each box is mounted on a set of shock coils. 2.  Install the honeycomb vertically to ensure maximum absorption during impact.

2
Cut honeycomb to fit into the shock coils.
3
