Standard AutoCannons

Standard AutoCannon (AC for shorthand) are the most basic ballistic weapon systems in Mechwarrior: Living Legends. They represent various auto-loading burst-fire and single shot ballistic weapons.

Overview

Old Warhammer variant firing an AC10

Standard AutoCannons deliver damage by firing ballistic high explosive kinetic shells at varying rate-of-fire. There are four classes of Standard AutoCannon: AC2, AC5, AC10, and AC20. The arbitrary number system roughly indicates the respective damage-dealing capabilities; larger numbers (AC20's) will deal much greater damage per ammo than smaller numbers (AC2's). Conversely, the weapon range drops for larger numbered AutoCannons. Because of the explosive nature of the AC shells, the splash damage can damage adjacent components of the hit asset.

In MWLL setting only Inner Sphere units still use standard AutoCannons, Clanners have replaced them with Ultra AutoCannons and Lubalin Ballistics-X AutoCannons.

Gameplay & Hints

AC2 and AC5

• Burst firing AutoCannon-2 and AutoCannon-5 both deal primarily Light Kinetic damage which is effective against Vehicles and Air units.

• Long range makes them suitable for direct fire support weapons, aiding friendly brawler units from a safe distance.

AC10

• The AutoCannon-10 shoots many high explosive shells with a very quick refire rate that causes the hit target to shake violently, disturbing their aim, also known as screenshake. Although the AC10 does jam, unlike Ultra AutoCannons, it does not lose any damage output for doing so.

• Heavy Kinetic damage does additional damage against air units, but the mid-short range somewhat limits their use as effective AA

AC20

• The AutoCannon-20 shoots a single high explosive shell with a relatively quick refire rate that causes the hit target to shake violently, disturbing their aim, also known as screenshake.

• Heavy Kinetic damage does additional damage against air units, but the mid-short range somewhat limits their use as effective AA

Canon

Standard Autocannon

The first Standard AutoCannon was an AC5 introduced in 2250 by the Terran Alliance, and would be followed by the AC2 in 2300 (Terran Alliance), the AC10 in 2500 (Terran Hegemony), and the AC20 in 2500 (Lyran Commonwealth). The weapons represent a wide range of heavy ballistic cannon with varying rates-of-fire and calibers ranging from 30 millimeters at the lightest up to larger than 200 millimeters.

Among the Clans the Standard AutoCannon was phased out sometime around 2820 in favor of the newer Lubalin Ballistics-X AutoCannons and Ultra AutoCannons. Even in the Inner Sphere the standard AC only continues to remain in use due to lower cost of production and the introduction of specialty munitions which are usable only by these weapons.
