Not so sure if someone has posted this but if you are as a copilot on a jet and fire missiles without locking the targets, sometimes when it reloads after firing 4 shots it does not fire any longer but you can fire only when you are on the cockpit mode.
It is very annoying since your pilot might think that you are just for the ride lol..
