Because the Jupiter Empire had limited resources to work with, they designed their mobile weapons so that each area would have a specific use; the 'head' was reserved for sensors, the body held the pilot and generator, the arms were manipulators, and the legs were for movement. The EMS-06 Batalla was built around this and the intention of getting as much use out of the mobile suit as possible; as such, it has a relatively simple construction that could be easily altered to create new variations or individual customization, but because of this, it had no built-in weapons. To compensate, the Jupiter Empire military developed a wide variety of handheld weapons - its standard armament is a beam saber and a beam rifle, with beam Gatling guns and missile launchers also being seen but apparently limited to stationary use - and two sub-flight vehicles, the EMA-01 Acusirio and EMA-02 Thostede, that were outfitted with large anti-ship particle beam weapons.

What sets the Batalla apart from virtually all prior MS designs is its legs; it was designed to retract its legs into its thighs during use in zero-G environment, allowing for high-mobility flight. Unfortunately, this cruise mode also consumes more fuel, which, coupled with the short-range nature of its design, puts an absolute limit on the distance it can travel. (Their range appears to be so low that chasing after the Crossbone Vanguard is inherently impossible - they'll run out of fuel before they can even get close to the Mother Vanguard, let alone attacking it) Also, due to living primarily in space, the denizens of the Jupiter area apparently consider the feet of a mobile suit to be landing gear, and so the Batalla is likely not that useful in an atmospheric environment.
