ENE, LRM, AC, IF, and SRM being the most common ones for 'Mechs, I believe. Though, LRM, AC, and SRM probably wouldn't mean much, as only Inferno for SRM would actually have any effective meaning for the time frame.
One has to remember, Alpha Strike, and its BattleForce precursor, were created well after the Level designations were created, and so a "need" for such simple rules weren't as needed.
We may see something in the Alpha Strike box, but considering that it has Clan 'Mechs, I wouldn't hold my breath. At best, most of the special rules will be limited to Clan Invasion variants, at most.
