Service Arm

It is important when embarking on Military Research to understand the concept of the "Service Arm".

The army is divided in various "arms" or branches. Each has a responsibility within the Army infrastructure in the similiar way corporations are divided in Departments. Many of these units would be assigned where required to the Field Army.

 

Royal Artillery Responsible for Fire Support ,Anti-Aircraft and Anti-tank
Infantry The PBI "Poor Bloody Infanry". The Foot soldier.(US Grunt).
Airborne Paratroopers and Airmobile Infantry such as Glider Troops (Generally treated as Infantry)
Royal Engineers Responsible for such matters as bridge building ,mine-laying,disposal of unexploded munitions etc. (In WW2 these units were generally assigned to Divisions in the form of either "Field" or "Bridging" Companies.
