d. Chemical Company Decontamination Squad.
Chemical companies can reinforce the efforts of a battalion PDDE crew by sending one or more decon
squads to assist in operational decontamination. The preferred method is to use reinforcing decon
squads to set up separate operational sites rather than use multiple PDDE at one site. This preserves the
advantages of a small, decentralized operation.
The preparation stage, as its name implies, includes all of the actions that must be taken before any
operational decontamination can take place.
The contaminated unit commander decides to conduct operational decontamination, calls the battalion
TOC, and requests support.
The TOC directs the battalion decon crew to meet the contaminated unit. The unit chooses the location.
Battalion assets may not be available to provide operational decontamination support. In this type of
situation, the battalion coordinates with the brigade (or division) for assistance. The contaminated unit
generally should communicate with the decon crew on the admin-log net.
c. Site Selection.
The contaminated unit chooses an operational decontamination site, but it coordinates with its battalion.
The selected area should be configured so that little preparation is required. Generally, the contaminated
unit has the most complete knowledge of local conditions and is the best qualified to select site
locations. The unit considers the following key factors when selecting the site:
■ Good overhead concealment.
■ Off main route, but with easy access for vehicles.
■ Large enough area to handle vehicle washdown and MOPP gear exchange for a squad-size
element (100 square meters).
