Nonsense.

Oh and by the way:
At minus 20 you can fight.
At minus 25 it is becoming iffy.
At minus 30 all fighting stops because your too busy trying to survive.

Also, unlike some I could name, the British Army has a Duty of Care when it comes to the lives of its Men and British Health & Safety Legislation is there for a reason. It's there to make an Employer, which the British Army is, exercise due caution and keeps them accountable. If a British Soldier dies on exercise in peace time we want to know who, what and why.

British Officers are not Cowards, or soft, which is what you seem to be implying.
