When the Soviets went into Afghanistam they found themselves being plinked at range by old .303 rifles which only the full-fat .30 Russian Dragunovs and PKM machine guns could answer, so they issued more of those to the grunts. They also got interested in the 30mm AGS system as well...
Naturally the NATO forces with complete 20-20 hindsight of the Soviet experience (
) found themselves in
exactly the same situation when they decided to take thier turn in the country. Cue rapid reissuing of full-fat 7.62 weapons all over the place, and 40mm GLs too.
Remember - "Military Intelligence" is an oxymoron
