You will learn to hate security forces as a whole but shooting is a good time. K-9 and CATM are the way to go. I would much rather be K-9 though... A shred is the better shred! As for shooting, you will enjoy the .50 much more, and the MK19 is pretty fun too. Shooting HE is way better than that gay orange powder dummy round. Oh well, enjoy Security Forces Tech School... Let me know when you get orders... I may know some people where you are going. Good luck!
