As for the assault command I have only used it sparingly and only when the enemy is pretty heavily thrashed! Don't try it unles you have alot of cover fire becuse if the enemy suddenly pops up out of cover while your men are charging across the open....well you know what happens. Having said that it is a great way to deliver a coup de grace and maintain a speedy advance! also in urban environments I use it all the time to rush across streets etc.
