Throwing smoke (special dodge) isn’t an attack, but can benefit from speculative fire and surprise shot rules. 6th Sense can only be used against attacks. Question: Trooper A is camouflaged and behind enemy trooper B. Trooper B has 6th Sense level2. Trooper A places a smoke grenade so that trooper B is inside the template. Trooper B can’t declare BS attack ARO, but can declare Dodge. Not sure about the modifier. -3? -6?
