Played through in a SSP-99M suit with second gen Night vision, an Akm 74/2 tuned for accuracy with 100 5.45x39 mm rounds, an HPSS-1m with extended mag and weight reduction with 400 9x19mm FMJ, and a Knife.
If limited in choice of weapons and stuck between a choosing 5.56x39 or 5.56x45, the 120 rounds of 5.56x45 AP found in the storeroom might assist in making the decision.

Reran the missions with a SPAS-14 (w/100 mixed rounds) and a Viper 5 (w/400 rounds of 9x19mm FMJ).
