Battle Dress Overgarment (BDO)/Overgarment (OG84). The BDO is a camouflage overgarment
consisting of a coat and trousers. This suit is normally worn over the duty uniform, however, in high temperatures it
may be worn over underwear. In extreme cold weather, the BDO will be worn under arctic clothing for camouflage.
The BDO provides protection against chemical agent vapors, liquid droplets; biological agents; toxins; and
radioactive alpha and beta particles. The BDO is not intended to be decontaminated, reimpregnated, or laundered,
and should be properly discarded after exposure to chemical agents in accordance with FM 3-5/FMFM 11-10.
Contact with petroleum, oils and lubricants (POLs) will significantly degrade protection provided by the BDO. The
nylon/cotton outer layer is treated with a durable liquid repellent. Whereas it is water resistant, it is not water proof,
and protection may be degraded when suit is soaked. Refer to FM 3-4/FMFM 1 1-9 for protective capabilities.
