This Weapon uses the Blast Template—a 5” diameter circle. First, place the template’s centre over the target’s centre—this is the primary target. Place all templates from one activation’s attacks simultaneously. All Units and Zones within the template are now targets. Roll to hit once against each target for each template. If the primary target was Obscured, everything under the template is Obscured, otherwise Obscured is ignored. Roll D6 times per template against Infantry. If the primary target is a Vehicle with Large or a Zone, do not place the template but roll to hit D3 times. This Weapon can inflict Critical damage against Zones. If the primary target is a Sited Squad, do not place the template. Instead, roll to hit the Squad D6 times. Roll to hit the Zone once. If the primary target is an Aircraft, only Aircraft under the template and not flying high are targets. If the primary target is a non-Aircraft, aircraft are not targets.
