The Cardassian Mobile Beam Emitter was originally intended as a theater defense vehicle which would be placed on planets and moons to attack ships as they enter systems. It was never meant to survive direct combat, instead relying on a combination of an optimized low signature silent running mode, long range sensor baffling due to surface proximity, and scoot and shoot tactics. Surprisingly it proved itself valuable in surface to surface attack in several offenses during the Federation-Cardassian Wars where it was able to pop above a horizon to use its weapon on various targets.
The vehicle looks like a sinister modernist interpretation of a temple mated with a lighthouse, at the vehicle's pinnacle is a five sided deflector disruptor based on that of the Galor class. The Series 1 versions lack additional systems such as shields, secondary weapons, transporters, replicators and advanced surface detection sensor suites. Series 2 adds a powerful shield system, pyramidal phaser emitters for close in anti-shuttle and anti-personnel fire, a dedicated sensor suit for surface combat and food replicator.
