I have flown Rook for 2 years now, or thereabouts. I can honestly say I have never heard cuss words used by Rook players on any sort of regular basis. If it happens, it's a rarity.
All cussing amounts to is tough language, and shows how weak and scared the cusser is. It also begets more of the same, and since we don't like it, and don't want it to become acceptable, we usually let people know pretty darn fast to cut it out. We don't encourage it in our squad conversations.
What you say on Channel One is your business. Only don't be surprised if you get called on it at some point, if you use foul language on country channel. Especially vox, where anyone can hear it.
