Initially a test bed design for the RAC/5, the Baker was finally released by the NAIS for full scale production by Hawkings Consortium after the FC Civil War.

The Baker was built around an experimental autocannon variant that the NAIS was working on at the time, and they decided to try it out on a new chassis first in order to avoid the teething problems that were so prevalent with adapting weapons to current designs.
The weapon was later known as the Rotary AutoCannon, or RAC for short, and it would prove devastating during the savage years of the civil war.
The Baker had several backup weapons in case the RAC/5 jammed, an extended range large laser and two medium lasers. Hawkings Consortium installed their own versions of the weapons, which were well known for their durability and ease of use.
Hawk Wings 330 jumpjets were added on later to give the Baker some improved maneuverability, allowing it to jump 90 meters.
A fully functional ejection flight system similar to that in the Wolfhound and Hatchetman mechs allows the Baker pilots to flee to safety easily.

Bakers were utilized in the rapid advance into the Chaos March as coalition forces pressed into Word of Blake territory, fighting hard for every inch of ground.
Bakers were often used as throw away shock troops, charging into the midst of enemy forces and then unleashing a full barrage of laser and autocannon fire. Many Bakers were lost, but the special ejection system saved many lives. Those pilots would often be assigned another Baker fresh from the factories, and then continued on the attack.

Lieutenant Gary Mitch
A lance commander in the MIB, Gary is nicknamed 'Unkillable' by the other members of his regiment after losing more than 6 Bakers in all without suffering a scratch for the entire campaign against the Blakist jihad.
He hopes to keep his present Baker around a little longer than his previous rides.

Alongside several other mechs like the Musketman and the Gorgon, the Baker is being assigned as a 'trooper' mech to green mechwarriors. It is rumored that the production capacity for these mechs ran something like 60 per month, an incredible figure for any mech manufacturer. Certainly, the total number of Bakers used during the jihad is a good indication of the rumor's veracity.
Observers have also noticed that Hawkings Consortium should be producing far more of these mechs than it is selling to buyers in the Inner Sphere. It is rumored that the MIB are receiving the excess mechs, but they do not have sufficient pilots to man the extra machines.
