If someone is shooting at your people and hitting they must be within 100 meters, which is what ROE’s are generally written in. The 100 Meter limit in the ROE is to ensure the hostile is engaged instead of innocents nearby. The farther they are the more difficult it is to determine which of those people over there are shooting at you and the closer people twenty yards apart appear to be causing mistakes in determining who is associated with the shooter. In reality, who can honestly estimate distance when they are being shot at. If they are close enough to positively identify them as the shooter and what’s behind them it’s guns hot.

Incidentally, when I was packing my M-16 I would gladly have traded for the M-4. Between the collapsible stock and 5.5 inch shorter barrel it’s on hell of a lot more convenient climbing in and out of everything. Of course we always want the newest stuff but you’ll be retired before the MP-7 makes it’s way to harbor patrol.
