Name given to a Marine, usually a Corporal, in his young twenties with a serious of medical conditions. Most notably a shoulder that breaks with any movement. Do not expect any Hamilton's to be physically fit for any exercise or training. Hamilton's should be issued Life Alert's since they have a tendency to fall unexpectedly and become helpless due to injuries.

Pvt: Yes Sgt, apparently he fell in the his barracks shower and cant get up.
