TAVOR Battlesuit

Tactical Augmented V/ORION Operations and Reconnaissance Battlesuit, or TAVOR-25 is the standard base battlesuit used by V/ORION Supersoldiers. The concept was suggested by Kurt-051, and created basic design specifications and enhancements from Colonel Ackerson's base design. The design would be forwarded to Misriah, but would not be manufactured until 2547, for use by the first ORION-II Supersoldiers (partially to fill the ranks of the dead SPARTAN-III's.) This base armor design had basic protection, and was stripped down from the original design to make it lighter, and cheaper to produce.

The armour system is basically a modified Semi-Powered Infiltration Armour undersuit. Designed to be lighter and more flexible, arranged in a design to effectively disperse kinetic energy, and utilizes a refractive coating to disperse direct energy weaponry attacks. The armour is highly adaptable, in that it accommodates armour plating from all UNSC systems, though it is incompatible with MJOLNIR systems due to its heavy weight and power consumptions. It is however, compatible with lighter MJOLNIR systems such as the FJ/PARA supplementary armour plating.
For V/ORION Supersoldiers, the plating mounted consists of mainly SPI Mk. I Components, though it is up-armoured to harbor the breastplate utilized by ODSTs. Field Operators are permitted to purchase and customize their TAVOR Battlesuits, with other power armour components or simple bandoleers, TACPADs, Knives or UA Systems.
The base helmet of the TAVOR M25-A1 is only used as a thin, secondary visor with an integrated HUD, and as a HAZMAT system to protect the user from dangerous chemical weapons. The base helmet also includes communications equipment and a re-hydration system that consists of nothing more than a plastic tube that opens with sufficient suction force is applied. It also includes a basic temperature control system, linked to the rest of the TAVOR Armour system (which also provides a source of water). The several unnecessary components can be removed to allow the wearer to use a more protective helmet (such as the SPI helmet).
One of the most important systems kept within the TAVOR is the basic SPI photo-reactive panels, which has been slightly modified to be more resistant to both projectile weapons, and heated DEW's, the TAVOR, however only allows the camouflage system to run for several minutes at a time. The photo-reactive panels run alongside several other stealth systems.
The M25-A1 Battlesuit uses an unchanged SPI Fusion Reactor, and it is mounted on the back of the armour, connected by a series of titanium-L plates that protect the wearer's spinal cord.
