ARMOR is used to represent how hard your robot is to hurt. It is used along with the pilot statistic Defense to calculate how much less damage you take from a given attack; a high Defense will partially make up for an average Armor and vice versa.
Armor ranges from 1000 on a totally unarmoured mech to 3000 to a perfect defense.
1000-1200 - The most unprotected units in existence; many planes. Examples: F-28 Messer (Banpresto Originals), Methane Wanzer (Front Mission)
1200-1400 - Extremely weak armor. Example: Ball (UC Gundam)
1400-1600 - Very weak armor. Example: Vic Viper Humanoid (Zone of the Enders)
1600-1800 - Weak armor. Example: Rick Dias (UC Gundam)
1800-2000 - Average armor. Example: The Gundam (UC Gundam)
2000-2200 - Above average armor. Example: Alex Full Armor (UC Gundam)
2200-2400 - Strong armor. Example: GaoGaiGar (GaoGaiGar)
2400-2600 - Very strong armor; many battleships. Example: Mazinger Z (Mazinger Z), Kurogane (Banpresto Originals)
2600-2800 - Extremely strong armor. Example: Grungust Type 0 (Banpresto Originals)
2800-3000 - The most well-armored units in existence. Example: Giganscudo (Banpresto Originals)
