I was thinking of doing the Daimyo, but looking at the MUL there's variants I'm not familiar with. the 2KA and 3K
Does TRO:J have new variants, or is something weird happening in MUL land?
TRO Jihad: "by combining the ’Mechs previously found in Technical Readout: 3050 Upgrade , Technical Readout: 3055 Upgrade , Technical Readout: 3058 Upgrade , Technical Readout: 3060 , Technical Readout: 3067 , Technical Readout: 3075 , Technical Readout: 3085 , and Technical Readout: Project Phoenix "
EDIT Ah, sorry, misunderstood. The compilation TROs are just that, compilations, no changes or additions to text. The 3KA and 3K are mentioned somewhere (probably TRO3055/J entry for Daimyo) but don't have record sheets.
EDIT2 Hmm, weren't in TRO3055U.
EDIT Could be they're units alluded to in original TRO3055 perhaps, but very vaguely, and MUL team just created designations for them. There's some precedent, see the Huron Warrior:
http://www.masterunitlist.info/Unit/Details/4342/huron-warrior-hur-wo-r3lThis variant is only described in the 'Mech entry, designation is created by the MUL team.
