Availability Rating

Description

Availability Rating is a code used in the Classic BattleTech game indicating how common a class of Combat Support Vehicles, 'Mech, (or other) mounted equipment, or subsystems found in the same. Its primary function is to designate how rare the systems are in a particular time period in the BattleTech universe. A [[similar system was used in the MechWarrior, First Edition roleplaying game. Predominantly, a weapon will have three different ratings: one for Star League era, one for the Succession Wars era, and a third for the Clan Invasion era. However, starting with the release of Interstellar Operations in 2016, some equipment tables started indicating a fourth code representing the Dark Age era. As an example, a standard Sylph battle armor suit has an availability rating of X-X-F-E. It didn't exist in the Star League Era or Succession War eras, was nearly unique in the Clan Invasion, and was very rare by the Dark Age.
