Soldier Bathroom Etiquette

Guys,

When we are in the bathroom, it is a no talking, no eye contact environment. But what are the rules when you are out in the open air? What if your friends aren't trying to talk to you, but whispering into your helmet mic while circling you in a Blackhawk and recording you on infrared camera?

Honestly, if I was that guy, I would've just pissed in their general direction.
