Lunar Anti-Alien Artillery Gun
Successful colonization of the Earth's moon made the threat of alien invasion seem less ridiculous, and a number of response measures were developed and reviewed. After years of deliberation, the decision was made to install weapons capable of defeating the assumed defensive capabilities of an alien craft. There are four LAAAGs built on the far side of the moon, each on its own military post. The ammunition used is an armor peircing high explosive shell 2.75 meters in diameter. The barrels stand 110 meters off the surface of the moon, the breach and loading mechanisms underground. The guns and their respective posts are named Alexander, Barbarossa, Charlemagne, and Decimus. However, the common soldier more often refers to them as Alpine, Beach Head, Cobra Commander, and Destro. Each gun has been test fired between four and six times, with Decimus successfully completing only one fire mission. The guns were decommissioned by the Selenine government soon after it was formed, and remained so until brought back into service by the PDLR. The guns are currently manned by skeleton crews. Their exact capabilities and specifications are classified.
