How The French Military uniform evolved:

A long time ago, the British and French were at War. During one battle, the French captured an English major. They took the major to their headquarters and a French general began to question him.

The French general asked 'why do you English officers all wear red coats? Don't you know the red material makes you easy targets for us to shoot?'.

In his bland English way, the major informed the general that the reason English officers wear red coats is so that if they are shot, the blood won't show and the men they are leading won't panic.

And that is why from that day to now, all French army officers wear brown pants.
