About Tactics when assaulting prepared positions

[Mustang]

Fixed fortifications are monuments to the stupidity of man.
-Patton

What I always do is use a lot of smoke. Even in the more modern battles, the enemy is going to have a lot of units with vision less than 40. Smoking them off out of sight will allow you to kill the enemy piecemeal. In any situation, use A LOT of smoke.

Here's a little trick. If your unit runs into an enemy at close range, lay down smoke in front of you. The enemy will try to close with you and pursue, but can't see you because of smoke and will get ambushed. MGs, for some reason, make excellent ambushers, better than most infantry when you take cost into account.
