Thorough Decontamination.
a. Thorough decon is the most resource-intensive type of decontamination. These operations
reduce contamination to negligible risk levels. The use of these procedures restores combat power by
removing nearly all contamination from unit and individual equipment. Troops can operate equipment
safely for extended periods at reduced MOPP levels. A small risk from residual contamination remains,
so periodic contamination checks must be made after this operation.
b. Thorough Decon is done as part of an extensive reconstitution effort in brigade, division, and
corps support areas. It requires external support by platoon- or company-size elements assigned the
mission of NBC decontamination. These elements will require augmentation from supported units to
accomplish missions. The decontamination unit is in charge of the decontamination site and operation.
c. Forces coordinate decontamination sites with the host nation through civil-military liaison
teams. The commander of the decontamination operation takes positive action to prevent runoff and
contamination of civilian water sources.
d. The two techniques that are performed during thorough decon are:
■ Detailed Troop Decontamination.
The unit removes MOPP gear, monitors for
contamination, and decontaminates masks with assistance from a decontamination element.
■ Detailed Equipment Decontamination. A decontamination unit conducts equipment
decontamination with the assistance of the contaminated unit.
e. After thorough decon, the unit moves into an adjacent assembly area for reconstitution.
Support elements from the brigade, division, or corps support areas replenish combat stocks and refit or
replace equipment and personnel. The newly reconstituted unit leaves the assembly area fully
operational and fit to return to battle.
f. Thorough decon does the most thorough job of getting rid of contamination and its hazards.
But, this extensive an operation often is not possible. Many valuable resources are required that may not
be immediately available. The next best solution is to decontaminate only what is necessary to sustain
the force and continue to fight.
g. Every type of unit (combat, combat support, and combat service support) must develop its
own SOPs and methods for
