What most people call strafing, I often refer to as hit-and-fade tactics. Like laststrike I usually do this just to kill off some enemy infantry so that a) he won’t attack, or b) if he does attack he’ll make less of an impact. I find it really effective if you have a lot of infantry and a few supporting units (tanks, fighters, ect.) and the enemy is a little weaker than you. In a situation like that, you wouldn’t want to take the territory you’re attacking (the enemy counter attack would probably wipe you out) so by doing a hit-and-fade attack you can prevent him from attacking you on subsequent turns.
