United States Army enlisted manís garrison cap
This is a standard US Army garrison cap for the Class A and B uniform. Although a visor cap (service cap) is part of the official uniform, the garrison cap is used when walking around without a tunic, or if there is a chance youíll lose your hat in a barroom brawl. Garrison caps are inexpensive to replace, donít weigh very much, and can be easily tucked in a belt or shoulder-strap for safe keeping.
