1 relating to a non-combatant:
The only certain non-combatant role in the forces was in the Royal Army Chaplains' Corps.
About 850 women are officers, three of whom already command non-combatant ships.
Commonly, they felt alienated from non-combatant society, frustrated at personal failure, and resentful of inadequate government policies and pettyminded officials.
This made it difficult to differentiate between the soldier and criminal, foreign and local fighter, and combatant and non-combatant.
This domain independent system was tested on planning non-combatant evacuation operations, which remove non-military personnel from dangerous situations.
It was also pointed out that these trends were primarily noticeable in the 'security soft-spots' like the recruit training establishments and non-combatant units.
I think they may fall within two categories—those selected for non-combatant service and those for national service.
