Yo, It may be future warfare, but because it's of PMC's, weapon designs can vary drastically. For example, soldiers could be armed with anything from an M16A4 to a SVD Dragunov to a Benelli M2 all at once. Weapon choice varies. So maybe in the future, weapon variety depends on who is friendly or enemy.
