A few small added thoughts. I really think Maltz has gotten most of them though.

On [Shield too big? Shoot their back!]:
Now comes in 2 flavors: moving and stationary
Have enemy troops chase bait while javelin throwers hit them from behind. Angle direction of bait away from javelin throwers so that chasing enemy units get the best "exposure". This way all those pila can be used up before any melee.

On [Shoot the parade!]:
Parade not forthcoming? Push a fast unit into the breach and parade will restart. Make sure you have enough time to retreat unit out of harm's way while still giving archers and javelin throwers enough parade "exposure" time. For best results: be patient (if you can afford the time) - the enemy will frequently stop a unit just in front of the breach and remain still till shot at once again (so make those stationary target shots count).

On [Encourage enemy general to commit suicide]:
Sometimes enemy generals are too tough. Soften him up first by running close to your archers and letting them shoot for fun. Have a spear unit near archer just in case enemy general changes targets (usually doesn't happen). Javelin throwers also do nicely but you'll have to micromanage your bait a bit more carefully when taking corners.
Once the AI is fixated on your bait he's usually fixed no matter what and once he's nailed onto the spears, even lighter troops have a fair chance of killing a general's unit.

On [Choke points with choking old man]:
Enemy choking old man in a threatening position near our troop stack without general? We can shove him in the direction we want by getting a troop to occupy the square he stands. Haven't seen the AI bribe towns yet in the early game so if you can end the shoving troop in a town he's safe as well.
