ACF-MKIIIa Arcandy Compact Breaker

Developed as an overall improvement of the Arcandy MKII Compact Design (which was further developed from the blueprints of the MKI Arcandy design but was never materialized), the MKIII “Breaker” is a high-performance unit that perfected the energy efficiency and high output experimented with the first two designs. While the number of field tests it actually underwent is unknown, the incomplete unit was eventually stolen by Daniel Sherman and upgraded with parts from the Urban Dreadnought to become the Hammerhead.

Technology and Combat Characteristics
The Arcandy Compact Breaker was designed as a general-purpose machine that solved every problem the Castel GT had. Being based from the Arcandite Core, it was very energy efficient and was given the METACOM system and HMT II Kit by default to increase its overall performance. While its armor and weapons were nothing special, it would be the inspiration for far more impressive equipment sets.

History
As the conflict between the Mercury Legion, Lance Core Remnants, and Unscathed Neo-Insurrectionists persisted, the UNI’s Arcandy Frame was definitely turning the tide of battle, costing the Mercury Legion more troops than they had expected. Thus, they decided to hire a band of mercenaries to infiltrate the UNI’s main base, Guardia 7, and eliminate their leader. Leading the Mercenaries was Daniel Sherman, a close friend of Jack Kendall. He accepted, and immediately set off towards the base.

Despite not having a Garrisai team, the mercenaries were still able to sneak past the UNI security and disable a few Garrisai while they were inactive. The team was able to successfully break through the UNI’s defenses and reach the main HQ, only to be stopped by Marie Winhart and Richard Longbow. The duo was able to take down many of Sherman’s men in a gunfight, quickly overwhelming them. Sherman, forced to retreat, ran to the Garrisai hangar and made his getaway in the Arcandy Compact Breaker.

The mission was considered a failure, but Sherman did in fact capture a newer copy of the Garrisai that the Legion was struggling so hard to deal with. Thus, it was disassembled and examined to create the new Legion RSF-MKIIIa "Ace Custom" types. Sherman and his team, as a reward for their efforts, were given their own Revolta Ace Customs in which they gladly accepted.

Trivia
- The ACB is theorized to have had been developed from the Bluemoon, as both machines strive to improve the performance of the Castel Ground Type, with the ACB being far more advanced.

- Another theory is that the Bluemoon is the prototype of the ACB, with the latter being the first mass-production unit-turned ace unit due to production lines being cut off.
