Based on the Model 3 Light Armor, this armor system has been modified to allow soldiers to perform unrestricted in battle. It uses CN-Gel to neutralize even the heaviest of xenomorph acids, turning their PH level to 7, which then glides right off the ultrahydrophobic surface on the armor plates. Its insides are lined with a combination of fiber and gel cushioning, serving as a storage for the CN-Gel, and protecting the user from heavy impacts. CN-Gel also serves as a great insulator, protecting the user from from the harshest of colds, to the blazing sun. Allowing the user to perform in any environment. The weight of the internal systems required the XM3-CL armor to be striped down tremendously, barely leaving room for any form of protection against projectiles. Making it unsuitable for combat against human combatants. The biological functions of XX-121 revealed to WY and USMC scientists the anti caustic properties in their bodily fluids and allowed them to create a version of the gel using XX-121 bio-matter, primarily their saliva, as a base for a Compound Neutralizing Gel, or CN-Gel. Resulting in a clear, thermoinsulating, thick, and overall economic gel. The Gel itself expands greatly when oxidized though the internal nozzles, allowing XM3-CL Armor system to be fully operational for weeks before needing to be refilled."
