One thing about the YA/ND, is since there are only the two units, they can hide very easily. Adding an archer unit, and now you have a full skirmish group, rather than just a nasty surprise. That takes a lot more management, and you might as well just break your army into two or three cohorts. The YA/ND tactic is when you have the bulk of your army visible on a hillside. The enemy will move to surround you main group, and will often not realize you have one or two ambush groups hiding out in the wilderness. Once the enemy engages the main army, you have your surprises dash out and hit him when he's not looking.

An important thing to remember that both YA and ND are fragile units. They can not hang in a fight very long. The main point of this tactic is to ROUT his troops, then cut them down as they flee. YA and ND both run quickly, so they are good at chasing fleeing troops, at less cost than cavalry. If they manage to form up against your raiding parties, then they will butcher you to the last man. Both YA and ND as essentially unarmored, so they will be cut down in a long battle. In the Single Player, heavily armored YA/ND are lethal! Actually, in the Exp Pack you WILL be able to armor your ND! Woo hoo! As you may guess, Shimazu is the best clan for this tactic, as they get boosted/cheap ND.
