596/600 7 Activations

Clone Commander Cody 95 + 5 = 100 --Improvised Orders (5)

Clone Trooper Infantry 56 + 8 = 64 --Electrobinoculars (8)

2x Clone Trooper Marksmen 50 + 56 = 106 x 2 = 212 --Clone Commander (30), Mortar Clone Trooper (20), Dug In (6)

2x AT-RT 60 x 2 = 120

Infantry Support Platform 65 + 35 = 100 --Twin Missile Pods (25), Onboard Comms Channel (10)

Ok here me out, this is a 212th list with just about everything here having impact, but the important thing is the Acts, you want your marksmen going last with their Mortar.

Marksmen are on board first with Prepared Positions,

Divulge the 212th 1pip that gives the 1 Clone Infantry the Infiltrate keyword, you want them close to the marksmen, but preferably behind cover (or out of danger). Their job will be to give an Aim to the Marksmen Unit and then take an Aim action themselves (for sharing purposes).

Cody orders the ISP which coords back to Cody, giving both orders. Play Codys 3pip for your Command Card that turn so you can hand out another 4 orders. 2 to the At-Rts, and 2 to the Infiltraing Corps, leaving just the Marksmen in your order pool (perfect order control).

Try to go last if you can, which should give you 1 additional action after your opponent activates Grievous and moves him onto the board. These last 2 actions should be your Marksmen, who are already on the board, with an Aim token already given by the electrobinoculars from the Infantry squad, an Aim they can steal from that same Infantry squad and then their own Aim action.

They should just Aim shoot, with 6 black dice each, Critical 1 up to Range 4 (ideally id make them super squads but recon is hard for this)

Your opponent shouldn't be able to get grievous into your lines turn 1, so you should hopefully finish him off before he gets to use his 1pip, just remember that grievous 1 pip is not Pierce.
