The Infiltrator Mk. II is a battle armor suit designed as a replacement for the earlier Infiltrator Mk. I. The original Infiltrator had long served the Armed Forces of the Federated Commonwealth (as well as DMI and MIIO) as a stealth suit that was a capable scout and could easily penetrate enemy lines. It did, however, have a number of drawbacks to its design and as one of the first generation of battle armor it no longer served the needs of the Federated Commonwealth's intelligence agencies sufficiently. Despite this need for a replacement, it took some time for the Commonwealth to respond as they had more units to equip with battle armor than any other nation and were still in the midst of rebuilding many units shattered during the Clan Invasion.[4][5][6]

Initial research and development on the new suit began in February 3056, when the Intelligence Secretariat directed the Office of Science and Technology to coordinate with the New Avalon Institute of Science on a replacement, but it wasn't until a year later when they received a startling breakthrough. The Gray Death Legion had located an ancient Star League vault on Karbala and retrieved several Nighthawk power armor suits from the hidden cache. Under orders from his liege Archon-Prince Victor Steiner-Davion, Grayson Carlyle was forced to hand the suits over to the NAIS in August 3057, where they were dismantled entirely. The destruction of the Nighthawk suits provided invaluable data to the NAIS scientists, who in January 3059 began producing prototype suits; full-scale production would finally start in March 3060.[4][5][6]

The Infiltrator Mk. II, nicknamed the "Puma" by many troopers, proved to be superior to the original Infiltrator in nearly every way except cost. This was especially true when performing "direct actions" as the Mk. II was far more combat-capable than the original. Demand for the new suit exceeded supply in the early years - both FedCom intelligence agencies bought up nearly half of all Mk. IIs produced - and this shortage was only exacerbated after casualties suffered during the FedCom Civil War. Despite this the Mk. II could be found in most Regimental Combat Teams and dedicated special forces units for years to come.[4][5][6]

Weapons and Equipment[edit]

The main gun of the Infiltrator Mk. II is a powerful Federated-Barrett "Magshot" Rifle mounted in the right arm. Rather than use a modular weapon mount, designers decided to give the suit a sniper weapon superior to all others on the modern battlefield. The Magshot has a long range for such a small gun, aiding a Puma trooper in his or her potential role as a sniper. The Mk. II also carries an Anti-Personnel Weapon Mount in the left arm for dealing with enemy infantry. Both arms end in Basic Manipulators which allow the suit to make anti-'Mech attacks or be carried into battle via OmniMech, although the right manipulator is fully encased within the weapon hardpoint when the Magshot is equipped.[4][5][6]

Although the Puma has just a top ground speed of 10.8 km/h, the inclusion of integral Jump Jets allows it to jump 90 meters at a time. The 360 kg of Standard Stealth armor the Mk. II caries not only allows it to withstand a full burst from an Inner Sphere Medium Pulse Laser and keep fighting, it also mimics the effect of a combination IR/ECM Sneak Suit, continually recharged by the suit to allow indefinite operation. Providing additional electronic protection is a personal-sized ECM Suite. Finally the suit includes an optional Parafoil attachment that aids in HALO drops.[4][5][6]


  • Sensor 
    The sensor variant introduced in 3063 removes the Magshot to make way for a more dedicated scout. It mounts improved sensors for this role. Offensively, the variant mounts an additional anti-personnel weapon mount and a heavier Machine Gun on the right arm, making it devastating to unarmored infantry. BV (1.0) = 29, BV (2.0) = 35[7]
  • Infiltrator CORAL INTENT 
    Originally an experimental testbed for Mimetic Armor, the CORAL INTENT prototypes, designed under supervising technician Kel Senn, were shelved until the Federated Suns received several Battle Armor C3 Systems from the Draconis Combine. As the C3 system couldn't function with the standard Infiltrator Mk. II's ECM Suite, the CORAL INTENT prototypes received the system. To provide some ranged attack capability, Federated-Barrett created the "Thunderstick", a clone of the "David" Light Gauss Rifle. The role of the CORAL INTENT prototypes is to sneak up close to enemy forces and provide targeting data to friendly units. BV (2.0) = 36[8]
  • Magnetic 
    This Jihad variant, first used in 3071, replaces the parafoil and AP weapon mount to make place for Magnetic Clamps.[9] BV (2.0)= 49[10]


  • In German products, the unit's proper name was altered to Grenzgänger II (Frontier Runner II).
