Then consider me in. Im thinking of making a breakthrough mech with heavy armor and stuff.

Glorious, that should fit in well with the current classification of mechs I'm working on.

Essentially, the breakdown of how NorAm mechs are classified is as such:

Heavy - Large mechs that serve support and mainline roles. These are the mechs that battles pivot around due to their size, armor, weapons, and more often than not, the sheer cost of using them.
-- Heavy/Assault - Heavies tasked with assault and breaching duties, these are the so-called "Tip of the Spear" machines that lead the charge.
-- Heavy/Support - These are the ones with long-range fire-support capabilities, typically equipped with howitzers and bombardment type weapons, they rely on lights and Commanders to relay information to them so that they can support the line.
Medium - Mid-weight mechs that serve multiple roles. Typically they are seen in packs, and serve the role of MBT in mech-warfare. Many strike a delicate balance between firepower and agility.
-- Medium/Frontline - These are the standard Mediums, typically decently armored and armed with a single main and twin secondary weapons, their strength lies in their tactical flexibility.
-- Medium/Assault - Heavier armored, and with a second primary weapon, these are essentially "Light-Heavies" that serve a role equivalent to modern day Tank-Destroyers.
-- Medium/Support - Lightly armored, but without the increased agility of lighter mechs, these support mechs typically mount heavy weapons in order to support the front-line from afar.
Light - Low-weight mechs that typically serve scouting roles, though some excel in other areas as well. Most lights will be thinly armored, but sport a higher agility than that of other mechs.
-- Light/Scout - Light weight and with armor barely equivalent to tissue-paper, the scout uses its wheeled chassis to quickly move across the battlefield and report forward positions of enemies.
-- Light/Support - Typically used in the role of recovery vehicles, Light/Support mechs can also utilize field-repair tools to quickly get a mech moving and back on the frontline.
Command - These are the mechs which mount the large communication arrays that relay information between all allied mechs under their radar range. Though the massive weight of the comms array typically means that a Commander is unarmed, there have been cases of a Commander holding a front with secondary weapons alone.
