If there is a FIST vehicle it has a crew full of FOs. Everyone knows how to use the equipment, especially the NCO on the vehicle (he is the one who operates it anyways) A company's FIST team is made up of 6-8 13Fs and an Artillery Officer 3 of those are sliced out to the line platoons and the NCOIC, FIST officer (FO), and 2-3 joes to crew the vehicle. A FIST assigned to an armored company is a little different, as there are not FISTers sliced out to each platoon. If there is a FIST-V present, there is an FO present.

All crew members of a FIST-V are all 13Fs. They are all trained FOs. It is not like there is an MOS for 'FIST-V Crewman that is not part of the Fire Support Team' Just like the crew on M2s are 11Bs (formally 11Ms before B,M, and H were all combined) The vehicle commander of a FIST-V who has around 10 years of experience as an FO and is an SSG he is the NCOIC of the FIST, is more than capable of calling for fire. As well as each line platoon HQ should have an FO (SGT or high speed SPC) attached. Those are the guys that call the most fire missions.

As a tanker I certainly would start pumping main gun at anybody walking out of a building leveled to that degree as they are not mortals.

I saw this film in the theater last year, it is a good war film if not somewhat over done in a few places for dramatic effect, but you need to have that to tell a good story.

FBCB2 is a stand alone piece of equipment that works in conjunction with a PLGR and EPLARS. The PLGR provides the positioning and the EPLARS is the data link. It is also connected to the intercom system so it can alert you if you are with in x meters of a reported enemy, but this is normally disconnected do to being extremely annoying, especially being near a minefield or something. It is a separate component from the radios. The data link and positioning is constant, but if you want to make a spot report or cff or something you need to send the message. In practice it is best used for navigation, as you see where you are on a map or sat picture in real time, and sending some of your daily reports like orange reports(supply status) to the PSG so he can send it to the 1SG. A lot of the other stuff it too time intensive to do in contact so your hand mic/boom mic is still the best. IVIS used the same data link system, but was like a 486 processor compared to some hardcore gaming computer of the FBCB2

IVIS is an outdated BLUEFOR tracker from the mid 90s that was on the M1A2. FBCB squared is its evolution. Only real useful thing with it was getting a quick grid to what you lase to call for fire. Other than that, in practice it was widely ignored by the operator but praised by the commanders.
