Let's also add the highly underrated Longbow to that list, though it's also in production at other StarCorps plants. Dual LRM-20s with a pair of LRM-5s, plenty of heat sinks, heavy armor, and two medium lasers to boot make the 3/5 moving 3025 variant a threat even in the Dark Age era. Then kick in all of the other variants, and you can provide enough shade for any number of Mech Spartans to fight in. Heck, we even made a mediocre Banshee variant, with the 3Mr providing enough firepower so that you can't ignore it.
Or for some great cavalry mechs, to all of the Ostol and Ostroc variants produced during Project Phoenix. They have everything from a 6/9 energy boat Ostol with TSM to a dual light Gauss model. We also have lots of jump capable Thunderbolts, it's direct fire cousin the Tempest, and the humble Orion. The list goes on and on. I play Marik for variety and the fact I look stunning in purple. I play Steiner when I want to advance in ranks of assaults and heavies, though with the influence of the Fedrats and the focus on speed, later era Clan Invasion and beyond Steiner has some amazing light and medium mechs.
