15.5mm HMGs (one coaxial, one on RWS, both use ETC propellants and fire iridium-osmium alloy projectiles at 2km/s), 2x 2cm Laser ADS, and 1x 65mm 'fuck you' coilgun capable of firing a 12kg iridium-osmium alloy dart (with electromotive 'jacket') at 2km/s (producing kinetic energy of 'only' 24 MJ, to put things into perspective, this is practically double the muzzle energy of various 120mm APFSDS shells).
Oh, it's only 65 tons, can achieve off-road speeds of 50km/h, and the vast majority of the models use a fusion cell powerplant rated at 2,750kW. Oh, and it can operate in space thanks to its heat management system.
