http://masterunitlist.info/Unit/Details/43/annihilator-cThis Annihilator lists its TRO as 3050U, but I can't find any mention of the C variant in the writeup in 3050U, and so its source should probably be set as Operation Klondike, where it is mentioned in the writeup Also, the Record Sheet Source says "RS3050Uu-C" but the C and C2 are in RS3050Uu-I. They're also in RSOK, but I'm not sure which one is newer at this point, but I would recommend RS3050Uu-I since its more mainstream.
http://masterunitlist.info/Unit/Details/45/annihilator-c-2The TRO for this is listed as "RS3050Uu-C" but obviously that's not a TRO, and should probably be set as Operation KLONDIKE, since that's where its mentioned. The Record Sheet source is technically correct, but it might be better to use RS3050Uu-I, since that's the more mainstream product.
http://masterunitlist.info/Unit/Details/1011/eyleuka-eyl-4aThs date is 3068, which is the Jihad Era, but the Era Symbol is the Civil War symbol. Since the design has Machine Gun Arrays, which debuted in 3068, the symbol should be changed to the Jihad Symbol. I suppose you could try to argue prototypes or something, but either way, the date and the Era Symbol should match.
