SR-M-3 Testudo

Harder to get on the black market than 5 tons of purest, solid Tungsten or heavy atomics the SR-M-3 Testudo is a state of the art war machine designed by Reptacorp from Prussen.
Testudo, as the name implies, is a slow and very heavy armored piece of equipment. Though this Mechanised heavy armor has seen very limited production, mostly due to its wondrous, complex design, it still managed to become a favorite among the Europa Federation Forces and many Rich Mercenarie cartels alike.
Proving the armor showed miraculous results by being able to take a series of heavy 40mm Armor-piercing rounds to the chest, surviving several plasma charges and even a direct hits from heavy rail cannons meant to take out light-medium mechs.
This ceramic wonder isn’t without its flaws… narrow nonaugmented vision and very low environmental resistance (for its class) being just a few them. Getting spare parts, if one is not in direct contacts with the military or the Raptacorp itself, are close to impossible. And the armor itself is practically immobile; with even the strongest athletes barely making the thing run at 4km/h. Frankly, most pilots would find any type of movement difficult at all. Any solo merc would quickly come to loath this armor, for all of its shortcomings are easily explained by simply implying that this armor is used by Federal Orbital Marines, where mobility makes way for fire power and survivability.
Speaking of firepower, besides any gun a soldier can carry in his arms, SR-M-3 was designed to use modular hand and shoulder mounted heavy weapon systems, such as the pictured here plasma gun. Other attachments may include autocanon, machine guns, heavy lasers and rail guns, even flamethrowers. Very often the armor is outfitted by very expensive energy shielding and additional arm mounded shields making it even more durable than it is already is.
