A little late to the party, but... I'd keep the Squire and find another way to add the Lancer. That way you get the extra inches of control area and re-roll any missed magical attacks. Maybe replace both Chargers with a Lancer and 2 Storm Gunners. With
Snipe they'll have a 16" range, POW 14 attack that will create an AoE 3 if you hit. Combined with
Assault you'll have a 24" threat range. And if Stryker knocked down your target with
Earthquake you will hit.
