From the update:
The Stormtrooper command squads are now available!
We also open up the Valkir Heavy Troopers! A core troop choice for the power armor sets. Still a work in progress, each box will contain 20 heavy troopers with 20 heavy rifles, 5 heavy grenadiers and 5 heavy flamers with enough ammo packs and accessories to load out your 20 man squad for the fight!
