Yep, as part of a TEAM with a variety of weapons, an AK is great. Out to about 250 yards max.
But I sure would not choose it to carry if I was alone, especially in open country.
In Afghanistan, of the available off the rack troopie long arms, I’d take a USMC M-16A3 with the 4X ACOG sight. Effective range 600+ yards.
A3 is good stuff, but if I’m alone in open country, and getting my pick of systems, I’ll take an M14 on an ALCS stock.
