About This File
Steven1918 and I have put together a comprehensive collection of WW1 anti-aircraft guns. A noteworthy feature is, for the first time, a selection of medium-level 37/40mm auto cannons that bridge the gap between low-level MGs and high-level 75mm AA cannons. The Maxim 37/40mm auto cannon, dubbed the "pom-pom" by the Brits, was used in various versions by all the major powers and was still in limited service early in WW2. Pom-poms will significantly affect a gamer's experience when flying below 5,000 feet, and could motivate a gamer to replay old campaigns - especially if he used to like balloon-busting. Now that balloons can be realistically defended, he may not like balloon-busting anymore. 
In addition to the pom-poms, there are multiple types of AA MGs. Also included are two types of optional gun pits: a C-shaped pit intended for use with AA guns, and a U-shaped pit intended for use with artillery, plus balloon winches for the major powers.
