Only... give it a drawback: Invisi-winians can't fire anything. They move normally, can't be seen by the enemy, but they can't shoot or use grenades until invisibility has expired. Would make for interesting surprises and chaos if they went un-invisible right under an enemy turret- which would cause chaos, but not necessarily the loss of a turret.
Artillery is already present in the form of Airstrikes, meteorites, and Nukes. What do you think Real-Life Airstrikes are? Sure they don't use a gun, but they're still considered artillery.
