Agree with D308. You don't fight where your enemy is strong and you don't insert yourself into their trap. Hit them where they are weak, alone, not expecting, unprotected. Then fade away. They can't put 100 people at every road block. They can't be every where and they have to go home or shop somewhere.

The enemy is the enemy no matter where he is or the time of day. Anyone who aids the enemy is the enemy and is worthy of aggression.
