You will probably never need to do a number 1 while in armor! You'll sweat so much, all the water will be lost through sweat. As for number 2, I've only needed to go once in all my 4 years of trooping. If that happens, you'll need to remove most of the armor.
Oh yes BOSS, I remembered you mentioned someone in the Legion makes the blaster holster. Can you PM his/her contact to me and I'll buy one from him/her. Thks.
