FM 3-5 Chapter 4
Thorough decon operations reduce contamination to negligible risk levels. They restore combat power by removing nearly all contamination from unit and individual equipment so troops can operate equipment safely for extended periods at reduced MOPP levels. There are three thorough decon techniques: detailed equipment, detailed troop, and detailed aircraft. The focus of this site will visit detailed equipment and detailed troop decon.

Detailed Troop Decon (DTD)
The major action in detailed troop decon is to remove contaminated MOPP gear to include the protective mask. The contaminated unit is responsible for setting up, operating, and closing the DTD in a thorough decon site. The chemical unit leader determines the general location of the DTD within the decon site. The chemical unit provides technical advice for the client unit. All soldiers needed to operate the DTD must be provided by the supported unit. The DTD has eight stations.
| Station 1 - Individual Gear Decon | |
| Station 2 - Overboot and Hood Decon | |
| Station 3 - Overgarment Removal | |
| Station 4 - Overboots and Gloves Removal | |
| Station 5 - Monitor | |
