EDIT- Due to popular demand (I think I've always wanted to say that...), I have been giving this design the photoshop-ification. It's about halfway finished right now, so it shouldn't take me much longer. Probably sometime Monday, if not tonight...

Although this suit was widely known for it's excellent ground combat capability, it hasn't been in action as much as the hype suggests. Even for a first generation warsuit, the Hawthorne was rather expensive to construct, and even more expensive to haul to the various battlefields it was designed for. However, the price was well worth it in the end.
Built specifically as a ground combat unit, the Hawthorne could operate in almost any terrain, save for water or extreme cold. It's entire body was layered with thick armoring, providing above-average protection from the majority of weaponry available at the time. Without energy weaponry, advanced explosives, or sufficient melee devices, enemy warsuits were generally forced into long-range firefights with the Hawthorne, which usually didn't go well.
Halfway through it's design process, Sentinel Mobile Armies (SMA) developed the SMA/WSW-12 Thunderer Machine Cannon, a beastly hulking firearm that provided superior firepower at ranges usually only touchable by sniper weaponry. Seeing the advantages of this powerful weapon, the Hawthorne's design was altered and completed on the basis of operating and handling this weapon at maximum efficiency.
The result was a thick-skinned, sturdy ground-pounder that could lay down fields of fire so dangerous that entire grid squares of battlefields could be denied to the enemy. To add to this style of battlefield control, the Hawthorne was fitted to carry hundreds of extra rounds for the Thunderer.
Because of these aspects, it was later designated as a fire support unit, to open the ranks for newer, faster suits. Even with how few of these units were produced, several could be found on the battlefield decades later, having survived many battles due to to their rugged construction and thick armor.
In this particular scene, a Hawthorne is docked at a field repair station, getting refilled on ammunition, propellant, and having minor maintenance done. The suit would stand with it's machine cannon in it's hand, with the pilot on guard, while this process was completed. This allowed the Hawthorne to rapidly re-deploy to engage targets wherever necessary, and provide security for the repair and refuel stations utilized by the Big Guns.
This one I'm particularly proud of, so much so that I included my weapon of choice in the photo-
