I'm Sheriff's. I still have discretion and the ability to make a decision without a field supervisor. I would not trade with LAPD for twice my pay.
Now as to your situation, the one factor that dictates every military op, regardless of doctrine is terrain. A natural choke point will force units to constrict- within reason. So something going up such as a ridge spur that would provide cover for one 113 to dismount its' squad and a hull down position for the M48...
I don't know if you've ever been out west but the landscape can be quite severe out this way.
Best of luck to you whichever branch you choose TL. Believe in the Army, and believe in your troops. Be the best soldier you can, no matter what your assignment. All jobs are critical to winning at one point or another.
