It in this type of game may works well as a cannon (as there is no space battle), it works as building that needs to be researched first (long research time), their shots are powerful and effective against vehicles (though they are enough for infantry-type), every shots need cooldown (betweens 4-6 turns), long builds time, long range with area damages, and their shots remains damages a little on few turns (called "electromagnetic remains").
This thing will surely get some tweaks, feel free to say your opinions (i feels it is OP anyway).
