I've used the ID10T myself, but I really like Squelch Grease.
Send the newbie down to the commo section to get a tube of squelch grease for the radios.
I can think of a few more, but I'll let the others share them.

Way back in my reserve unit, a fairly new Lieutenant wanted to take a vehicle out to see what the troops were doing. The First Sergeant was in the motor pool and told the Lt. that the vehicle the Lt. wanted was out of service because they hadn't replaced the winter air with summer air.

It actually took the Lt. a few moments before he caught what the 1st Sgt. was saying.
