So recently I played in a round robin styled tournament against all the factions. My list was not defeated once, and I almost always tabled my opponents (who are significantly more experiences in this game than I)
Basically what I did was I waited around a little bit, prioritizing veers' order in order to set up units with an aim, and then as soon as he started to move closer with his units, activate my army and slowly kill his units off, by getting the first overwhelming volley every time.
The list runs as follows:
General Veers (vanilla) 80Pts
DF-90 Mortar trooper (vanilla) 36Pts
Shoretroopers (52) + Targeting scopes (4) + T-21b Trooper (32) + shoretrooper (13)
Storm Troopers (44) + Targeting scoped (4) + DLT-19 Stormtrooper (24) + Stormtrooper (11)
ATST (170) + Imperial Hammers Elite Armour Pilot (10) + 88 Twin Light Blaster Cannon (20)\
**Veers command cards, plus the vanilla set**
