VG/Armor

Combat

 * Damage Protection = This value represents a percentage reduction of the damage that successfully affects a character's health. Usually shields must be depleted first. Any damage inflicted on the character is reduced by the listed percentage. In the case of multiple effects the percentages are calculated in a series.
 * Shields = This is the character's first line of defense, and represents the total amount of damage that a character's armor will absorb before affecting their health.
 * Tech / Biotic Protection = Much like Damage Protection is a percentage reduction of damage sustained, Tech / Biotic Protection reduces the amount of time a character is affected by hostile abilities.

Non-Combat
Some armors have certain properties beyond those three when worn, such as increased protection from or immunity to environmental hazards on dangerous worlds or health regeneratiton.

Calculation
Light: Base value, plus increase * level (i.e. I=1, II=2, III=3, etc.), round down. Medium: Damage +6 ranks, Shields +1 rank, Tech/Biotic -5 ranks. Heavy: Damage +14 ranks, Shields +2.5 ranks, Tech/Biotic -10 ranks.
