Manufacturing started in the 1960s and this model is from the early 1980s. It is based on the M105A2 cargo trailer and features a self-contained inflatable nuclear-biological-chemical (NBC) protective shelter built in. The trailer contains a small generator, climate control, and filtration system to support the decontamination chamber and main tent. Consignor research is included.

The system has not been checkered but seems to be complete.
