Am I qualified to do a FAST or am I going to go PRP? You have to be an 03 to go to FAST on an operational level. PRP commands will take NCO's as non 03's and then you just have to learn the ropes.
Also what are some of the things that i can expect from the school, like am i going to be able to have a POV? The school isn't that tough, especially for an NCO. It's challenging and guys do fail, but as long as you go there focused to finish the school then you should have no issues. From what I remember, no POV's are allowed in any schoolhouse environment, and no you can't have one at the basic security forces school.
I would like to deploy with security what are my chances for that. Not very likely as a "regular" security force Marine. FAST Company has different missions and they deploy for the mission, but the rest of the Marines from Marine Security Force Battalion are there to protect hard assets.
