One last NZ question:
What's your NZ section layout? How did you maneuver when you move?
I think some of the American doctrine has been built around breakdowns by 2s (so you always have a buddy).
Back in the late cold war, our infantry reserve unit used about a 9-11 man section with 3 with the SAW and the balance with rifles with the notion that we'd generally articulate in 3s (to move, one cover, or two cover, one move). Back then, we had semi-auto FNs (SLRs in Brit parlance) and a heavier FN C2 with a 30 round mag (I think, been a while) for a SAW (which was not anywhere like having the C9 SAW we have now - which is the US M-249 SAW which is belt fed). The only really fun thing about the FN is when we did obstacles, it was sturdy enough that one infanteer could grab the barrel, another the butt, and a third could use it as a step to scale a wall. But in terms of ammo carried, accuracy (esp in standing or kneeling) and being a bit less picky, the C-7 was a great improvement over the FN.
We also did a lot of 'advance to contact' work with the mantra "up-he-sees-me-down" to go from prone to prone in a matter of a few seconds after a small displacement. I understand that kind of went out of British service after the Falklands and Goose Green - too slow. I saw combat videos from Afghanistan and the movement and fire was much tighter and more coordinated (from what I saw). Mind you, back in my day, a flak jacket would stop fragments but not rounds, so you didn't wear one. That made you faster than someone wearing a kevlar vest with front and rear plating today.
