Not true actually. Uniforms were originally intended to enable the identification of friendly forces on the battlefield and have since become a method of personal concealment. Shaving and keeping hair short was for hygiene purposes - it prevented the spread of fleas and lice and subsequently allowed medics to treat wounds without having to remove hair from the area.
So going on your statement above, why do we bother to wear rig in camp? (Sorry, wear uniform on base).
Nice come-back but I dont think you've really made a convicing argument regarding military people being grossly overweight.
Are you saying its ok for military chaps and chapesses being grossly overweight regardless of them being able to do their job?
Is being military just about being able to do your 'designated job spec'?
Surely the fatties should be doing something about it rather than spending all their time posting about why they should be lard arses on here?
