Designation: SCAR CBR Mk. 1M Marine Amphibious Armor (MAA)

Type: Hard Amphibious Armor

Year Introduced: 2024

Weight: 8.6 kg

After the introduction of their standard battle-armors, the UEDF went on to design armors for those armies needing environmental suits. Among these branches was the Naval Division. Like the non-environmental CBR-series TA-P and ITA-P armor, the Hostile Environment Armor – Plate (HEA-P) series armors were distinguished by branch of service and the pilot’s gender, and the helmets by rank – officer, non-commissioned officer, and unrated enlisted. Unlike the normal CBR armor types, these armors were completely self-contained, and could support the wearer for some time without external support. Additional support was possible through the use of backpacks, and this was necessary for long exposure to hazardous environments.

The CBR Mk. 1M Marine Amphibious Armor (MAA) was designed for use by the Naval Division’s (NAD) Naval Infantry units. These units filled the same role as the Marine Corps of Earth’s pre-war militaries. As such, the NAD needed a fully amphibious armor for amphibious assaults, clearing beachheads and underwater demolitions. The CBR Mk. 1M fulfilled this role through the use of an integrated dry suit, swimming fins and a positive buoyancy system built into the chest. These features allowed the Naval Infantryman to operate in water up to a depth of 35 meters. On land, the CBR Mk 1M was comparable to the CBR Mk. 1 Tactical Body Armor – Plate in both weight and mobility.

The CBR Mk. 1M was composed of the same plastic-ceramic composite material as the rest of the CBR series. This material was optimized for maximal resistance to penetration and thermic explosive damage for minimal weight. The armor stops most small arms fire and grenade and shell fragments, and provides poor to fair resistance against heavier infantry weapons, such as a 12.7mm machinegun round. The CBR Mk. 1M armor consists of separate leg, arm, torso, and helmet units, and covers the entire body.

The CBR Mk. 1M Marine Amphibious Armor (MAA) has the following features:

Positive buoyancy system built into the chest plate. This consisted of a large inflatable bladder with an independent nitrogen supply that could inflate and deflate to match the wearer’s needs. Typically, the system would operate at neutral buoyancy for SCUBA operations. It could inflate to the point of positive buoyancy if needed, allowing the wearer to float on the surface of the water. The system was not automatic, and the wearer was required to fine toon the system for his individual weight.

Ridged swimming fins. Detachable fins were built into the feet to allow the wearer to swim in the same way as a conventional SCUBA diver.

Thermal regulation system: Integrated dry suit with full temperature control, by the use of Peltier-electric cooling units in armor, conducting heat between the thermally conducting inner and outer layers of the armor. A simple reversal of the voltage can alternate the armor from heating to cooling the pilot. Between the thermally conducting layers on all these pieces, and on the inner surfaces of all other pieces of armor, is a thin insulating layer, designed to minimize non-directed heat transfer. The Peltier-electric units are powered by small batteries in the armor units that contain them and are designed to assist pilot comfort in hot and cold climes. The units are insufficient for protection above 75 and below -55 degrees Celsius. Heat resistant up to 500K for brief periods.

Pressure resistance: The suit is rated to a pressure of 350 kilopascals.

The LAR IX Draeger rebreather. A closed-circuit SCUBA device. Running on 100% oxygen, all expelled breath is recycled into the closed circuit where it is filtered for carbon-dioxide. The result is a complete elimination of expelled bubbles which makes the Draeger ideal for clandestine amphibious operations.

Tactical Helmet: The helmet has a removable face-shield with variable-tint photochromic polarized polycarbonate eyeslits. Contrary to popular belief, the eyeslits do not have integrated night vision or IR spectrum imaging. The NVG-647 Amphibious Night Vision Device can be attached directly to the faceplate, providing both of these features.

Tactical Radio: Narrow band, short range tactical radio for communication at the platoon level. The microphone and speakers are built into the helmet. This communication system will also wirelessly synch with longer range tactical radios, both dismounted and vehicle mounted. The system incorporates ultra-low frequency (1Hz to 3kHz) for short range underwater communication.
