[@AndyC], what would be an average Mech?

As @wikkit mentioned, Wasps, Stingers, and Locusts are all pretty ubiquitous, as are Griffins and Shadow Hawks. Warhammers and Archers are a pretty common sight for heavy mechs, and if there's an assault Mech on the field, there's a pretty good chance that it's a Stalker.

There are also Mechs that are far more common with specific factions. House Kurita, for instance, will field whole companies of nothing but Jenners and Panthers. House Davion, on the other hand, is big on autocannon-centered Mechs like the Jagermech, Centurion, and Blackjack.
