This document provides the Installation Instructions for the Armor Upgrade, Generation III
Steel Overlay Kit (the Kit) for the Palletized Loading System (PLS) vehicle. This Kit, which is
manufactured by Simula Aerospace and Defense Group, Inc. (Simula), is composed of various
armor panels that can be easily attached and detached from the PLS and stored in dedicated
storage containers when they are not required.
This Kit provides the PLS with improved ballistic protection against improvised explosive
devices (IEDs), light artillery fragments, and 7.62-mm Ball projectiles. The Kit consists of six
armor panels (three panels for the right side and three panels for the left side), mounting
spacers, and the necessary mounting fasteners (see Figure 1-1).
1.2 CRATING / UNCRATING
Each Kit is contained within a protective shipping container. These containers provide the Kit's
armor panels with protection and security when they are not installed on the PLS (see Figure 1-2).
Because of the weight of specific armor panels within the Kit, care should be taken during
removal of the panels from the containers or replacement of the panels back into the containers.
Two personnel and/or mechanical aids (hoist, forklift, etc.) are required during the installation or
removal of the armor panels.
1.3 SAFETY CONSIDERATIONS
The weights of some of the components within the Kit are heavier than allowable for one or two
personnel, and the metal armor components may have sharp edges. Appropriate lifting and
safety equipment, manpower, and safety precautions shall be utilized to ensure that no injuries
are incurred during the installation or removal of the armor panels onto the PLS or during the
removal or replacement of the panels into the shipping containers. Warnings, Cautions, and
Notes are provided in these Installation Instructions, as appropriate, to advise the maintenance
personnel of information necessary for the installation or removal of Kit components.
