>>27702493Machine guns are used to suppress and fix an enemy. If the enemy is suppressed and can slip away, you have not neutralized them. The most well fortified and heavily gunned outpost can be destroyed by artillery or simply avoided.
Having a bunch of machine guns strains logistics, and simply makes you a sitting duck for artillery.
You NEED manuever. You need light infantry with light weapons that can bound over terrain and flank, close with, and destroy the enemy while the machine guns suppress them.
