Sure, but we should be able to see if 0331 guys and the like have a higher incidence rate of suicide overall. Presumably they are spending far more time on these platforms than SOF.

The amount of shooting 0311 Rifleman does is fraction of what SOF does. The problem is accumulation of damage and no healing periods.

As I said, we don't if calibers below .50 cause significant damage when shooting in excessive amounts. Trying to figure it as a layman is useless. It's better to show epistemic humility than try to assert one way or another.

The FN Minimi (M249) fires 5.56. The others fire 7.62, not 7.52.
