The British Army's rules of engagement in Afghanistan are unilateral, and bounded by the restrictions imposed by international law (often more restricted that is required).
To be a member of the serving forces is to be expected to follow those rules, in all circumstances.
The rules are written with these circumstances in mind. It's not as if the government and army leadership didn't have shooting and war in mind when they wrote the rules of engagement for the conflict in Afghanistan.
