USE

There are at present in service use only four smoke-designated bombs, exclusive of those bombs containing smoke spotting charges. These are the 4, 100, 120, and 500 lb. smoke bombs. The bombs are used to lay smoke screens to con-ceal troop movements.

FUZING

These bombs are fuzed in the tail, except the 120 lb., which takes a nose fuze.

CHARACTERISTICS

Smoke bombs are colored dark green overall with a red band around the body. The 4 lb. bomb is merely a cylindrical sheet metall can; the 100 lb. is the same size and shape as the 45 lb. incendiary, with a white phosphrous filling; the 120 lb. bomb consists of an outer container and an inner smoke container which is blown out of the rear of the container by an ejection charge.

The 4 lb. bombs are preferably carried in Cluster Projectile No. 6, Mk I, while the 100 lb. and 120 lb. smoke bombs are generally carried in the Small Bomb Conatiner 250 lb. The 500 lb. bomb is sus-pended individually in most 500 lb. bomb stations.
