In a permissive environment, nobody applies the wood better than the Ghostriders. "Son of Spectre" is due out soon, deploying a COIL laser. It'll be just like burning ants with a magnifying glass, just on a grander scale.
105mm is for hardened targets, (bunkers, buildings, tanks etc.) 40mm and the 105mm are nothing more than exceptionally accurate artillery. 20mm or 25mm is for red misting troops caught in the open.
More Ghostrider film, 12 megs worth.
