Sure-fire way to win - mass riflemen or assault teams, send them over the top. When they've all fired and are reloading, pause for about 2/3 seconds, then resume. They will all have reloaded whilst you have paused. This means your men can get 3/4 volleys in before the enemy can get 1 or 2.
had to reload this a million times, keeps happening - chapter 5, second industrial area, i click on the metal rod and it just disappears, doesnt go into my inventory! help :((
