Lance Building: Roles, Synergy, and Thinking About Your Force

A lance is four 'Mechs. Getting four 'Mechs that work together rather than four individuals who happen to share a map is the difference between a functional force and a frustrating one. Here's how to think about it.

The Four Roles

Not every lance needs one of each, but understanding the roles helps you understand what your force can and can't do.

Scouts and harassers are your lights and fast mediums — Locusts, Commandos, Jenners. They push forward, spot enemy positions, threaten flanks, and draw fire that your heavies don't have to absorb. They die fast if they get caught, which means using them well is a skill in itself.

Skirmishers are your mobile mediums — Griffins, Shadow Hawks, Wolverines. Fast enough to reposition, armed well enough to do real damage. They fill gaps, exploit weaknesses, and provide flexibility. Most balanced lances have at least one.

Fire support sits at range and contributes damage without taking it — Catapults, Archers, anything with LRMs. They're force multipliers when they have lines of fire and useless when they don't. They need protection.

Brawlers close distance and apply overwhelming force — Thunderbolts, Marauders, Atlases. They're slow, they're tough, and they're the reason opponents have to commit. They anchor a battle line.

The Standard Balanced Lance

The classic BattleTech lance structure is one light or fast medium, two medium-to-heavy skirmishers, and one heavy brawler or fire support. This gives you speed, flexibility, and hitting power in roughly equal measure. It's not the only way to build but it's the default for a reason — it works across most scenarios.

A simple example from the starter set: Locust (harassment), Wolverine (skirmisher), Griffin (skirmisher), Thunderbolt (brawler). The Locust threatens flanks and draws attention. The Wolverine and Griffin manoeuvre and engage at range. The Thunderbolt closes in and finishes fights. Each 'Mech has a clear job and they complement rather than duplicate each other.

Battle Value

Every 'Mech has a Battle Value (BV) — a number that represents its combat effectiveness. BV-matched games are the standard for fair play. If one player has 4,000 BV and the other has 5,000 BV, the higher-BV player has a significant advantage.

Heavier isn't always higher BV. A well-armed fast medium can have higher BV than a slow assault with outdated weapons. BV accounts for speed, armour, firepower, and heat capacity together. Pay attention to it rather than just tonnage.

For casual play, matching within 10–15% is close enough. For anything competitive, match BV within 5%.

Avoiding Common Mistakes

All-heavy lances sound tough but play slowly. Four assault 'Mechs can't manoeuvre, they block each other's lines of fire, and a single fast light can run circles around them pulling attacks from unexpected angles. Speed matters.

All-ranged lances fall apart in close terrain. If your whole lance is built around LRMs and the scenario puts you in an urban map, you're in trouble. Keep at least one 'Mech that can work effectively at short range.

Duplicating roles wastes synergy. Two Catapults in a lance look good on paper — that's a lot of missile fire — but they both need the same thing (range, clear lines of fire, protection) and they both struggle with the same problems. Variety is resilience.

A Note on Heat

When building a lance, consider heat as a collective resource. A lance where every 'Mech is heat-intensive is going to have turns where nothing can fire effectively. Having some 'Mechs with efficient ballistic or missile loadouts alongside the energy-heavy designs gives you more sustained firepower over a full engagement.

This isn't theory — it's something you'll notice after a few games. The lances that win sustained engagements usually have better collective heat management than the lances that look most impressive on paper.
