Fire Mission 

1) The annoying thing the AFATDs says when data is sent.
2) A Call for fire (artillery) despite being the oldest forms of area fire, arty is still an effective means of illumination, suppressing, screening and destroying a target of opportunity in a quick and timely means with variations in shell and fuze combinations. Also specific rounds can be used to minimize colateral damage.

Command: Hey why did we shoot a fire mission?
Fister: Because we wanted them dead?
Command: aijgoaihghegloaeiojoawet283u59235!!!!!1!!!one!!1!
Fister: Ok but they're dead now so....

Command: Well we wanted helocopters to kill them because we wanted to be involved and make ourselves feel important.
Fister: They can still do a battle damage assesment?

Fire Mission Cock Block 

Any form of delay or douche-baggery resulting in either a check fire or end of mission. Usually employed by helicopters flying around knowing the gun target line and blatantly disregaurding it in order to try and steal a kill from artillery. This is done because frankly helocopters just aren't sneaky enough to get their own kills, and staff officers swing from air support nuts.

Fister 1: Shot tgt#1234, check fire we have helos on the gun target line.
...an hour later.
Fister 1: Cancel check fire, end of mission this shit took way too long and helos scared them away.
Fister 2: Dude we just got fire mission cock blocked!
