Military Organisation and Structure
Army: Organisation
The Army is made up of several functional groupings, known as corps (pronounced cores). These corps can be classified into two broad categories: the arms, or combat, corps and the service, or combat support, corps. The arms corps are those which are directly involved in the fighting, while the service corps are those which support them.
