A must read!!!!!!

SHUT THE FUCK UP
The number one thing to remember whether on the radio or not, is shut the fuck
up. You people gossip like little kids about the most meaningless shit imaginable
and it gets people killed because you gave away the team's position or prevented
someone from giving a contact report over the radio. When you DO talk, be clear
and concise and don't spend minutes saying what you could have said in three
words.
MAKE SURE YOUR DAMN RADIO WORKS
Be on the same channel as the rest of your fireteam and do a radio check to
confirm before you head out. If you're the leader, make sure you have radio
contact with the rest of command. You'll need to tell them when you have
accomplished your mission or when things have changed, or to receive new
orders.
When you're talking on the command channel, prefix everything you say with
“Command” so everyone's clear and no one confuses it with anyone else they
might be talking to. Like, “Command, this is Bravo fireteam. We are entering the
town from the north.”
