Okay, the more I look at FWL Anvil Lances, the more I think Moltkes (M2s and M3s at least) may be utter BEASTS in such a formation. Long story short, every turn half the tanks can stand still for a damage bonus, or get a to-hit bonus in exchange for a very slight damage reduction while still moving.
This works for any lance where at least half the units mount cluster cannons, SRMs...or LRMs. If you don't care about indirect fire as much, imagine what your missile lances can do... >:D
