Missile troop order/protection questions

[PvK]

Ya, I think a good one is also for a thug or melee commander perhaps with some men on Guard Commander: (Attack)(Attack)(Attack)(Attack)(Attack)(Attack Closest)
My theory is that this gets the thug/commander to re-consider his target each turn, which helps him adapt better to changes in the first six turns, rather than chasing whoever was closest on turn 1 or turn 3. I'm not sure my theory is entirely valid, though.
