After the introduction of their standard battle-armors, the UEDF went on to design armors for those armies needing environmental suits: the Tactical Space Corps and Tactical Armored Space Corps, and for the REF’s Tactical Naval Corps and Marine Corps. 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 were capable of supporting 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 HEA-P were built in two versions: the original CBR Mk. 1E Hostile Environment Armor – Plate (HEA-P) and the CBR Mk. 2E Hostile Environment Armor – Plate (HEA-P). Both types were designed by the state owned Southern Cross Armament Research Corporation, and constructed by sub-contractors. Since there were no significant difference between the -1E and -2E models, other than a significant 3 kilogram reduction in weight, both will be addressed in this article.
Like the TA-P and ITA-P armor, the HEA-P armors fell out of use soon after the Invid occupation of Earth and the destruction of the Southern Cross.
The HEA-P armors are composed of a plastic-ceramic composite for maximal resistance to penetration and thermic explosive damage for minimal weight. The Mark 1E armor (which is essentially considered Light, though it is not designated as such) and the Mark 2E Type 2 Light TASC 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 Mark 2E TSC Heavy armor stops most small arms fire and grenade and shell fragments, and provides fair to good resistance against heavier infantry weapons, such as a 12.7mm machinegun round. The HEA-P armor consists of separate leg, arm, torso, and helmet units, and covers the entire body.
The CBR Mark 1E and 2E armors have the following features:
Magnetic Interface Locking System (MILS): Powerful electromagnets to secure various Extra-Vehicle Activity (EVA) space booster packs. Optional utility belt that mounts to the waist. The space booster pack is 32kg and contains reaction mass for 200 mps delta-v.
Thermal regulation system: 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.
Full pressure control: The suit is rated from a vacuum to a pressure of 350 kilopascals. Independent Oxygen supply, 60 minutes maximum.
Tactical Helmet: The helmet has a removable face-shield with variable-tint photochromic polarized polycarbon eyeslits. Contrary to popular belief, the eyeslits do not have integrated night vision or IR spectrum imaging. The NVG-645 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.
Vernier-thrusters: TASC armor is equipped with 1mps Vernier-thrusters in the ankles.
Integrated G-suit: The Mark 1E and Mark 2E TASC armors had integrated g-suits composed of air bladders in the legs and torso that automatically inflated in order to assist the pilot in dealing with high g maneuvers encountered in space combat.
CB-S armored shields: Different designs existed for both the TASC and TSC. All were large arm-length shields with 25mps Vernier thrusters built into them.
