The HBK-4G Hunchback is the lightest mech to carry the deadly AC/20, a weapon capable of turning even the heaviest mechs to molten slag. Weighing 50 tons and costing a little over 1000 BV, The HBK-4G is well-armored but slow for its size. Regardless, the Hunchback is a fearsome mech that is all but guaranteed to draw enemy fire - lance commanders must take extra precautions to ensure the HBK actually gets into range before being knocked out of the fight.
The distinctly recognizable CRB-20 Crab is a scrappy 50-ton workhorse that exclusively packs energy weapons that favor a mid-range firefight. A high top speed allows the Crab to avoid incoming fire and conduct hit & run maneuvers with ease. At nearly 1200 BV, the CRB-20 rivals some heavy mechs in terms of cost, but the sheer toughness of this mech make it well worth it. Either as the lead mech in a light raiding lance or a frontline choice in a heavy lance, the CRB-20 Crab is an effective choice.
The CN9-A Centurion is a capable 50 tonner that provides effective support for medium and heavy lances. It is slow and notably fragile under concentrated fire, but a versatile armament allows this mech to contribute to the fight at all ranges. Costing a modest 945 BV, the CN9-A is a bargain mech capable of dishing out considerable damage for its weight class. In short, this mech is a quintessential glass cannon.
Iconic in design, and feared on the battlefield, the CPLT-C1 Catapult finds itself at home in lumbering assault lances as easily fast-moving medium strike groups. Although this mech is well-known for its fire support capabilities, the Catapult can also hold its own at short range. It clocks in at just under 1400 BV, making it among one of the most expensive heavies of its era - and perhaps a little overcosted.
Weighing in at 80 tons, the ZEU-6T Zeus is a reliable, hard hitting, and durable frontline mech. It features a diverse armament capable of laying down punishing fire along with the mobility and survivability to contest key objectives. At just over 1400 BV, the ZEU-6T is a solid choice as the centerpiece of a heavy lance, or to round out an assault unit.
