The exact names for this Armor for each PMC:
Raven : Reinforced Composite
Reinforced composite is made of the same bullet-resistant material as mesh composite armor, but with additional elements of alloys and ceramics that improve protection while reducing some mobility.
S.V.E.R. : Ballistic Vest
The ballistic vest is a combination of steel plating and bulletproof material, making it a good balance between mobility and protection.
Valor : Reinforced Fiber
Reinforced fiber armor increases the level of protection at the cost of some mobility, making it a good choice for soldiers who need to remain mobile during a firefight.
Raven Medium Armor (Reinforced Composite)
S.V.E.R. Medium Armor (Ballistic Vest)
Valor Medium Armor (Reinforced Fiber)
Enhanced Medium Armor costs 8cc to use, and offers better protection than the Ballistic Vest, but with no movement penalty. You can survive two Tier 1 sniper rifle shots and still have enough health to get clear and heal yourself. This armor is invaluable to players who use hard-charging, front-line tactics.
