I think the sword-cross emblem is for anti-nation force. In the beginning of episode 1 of macross zero,there is an epic dog-fight between UN F-14s and Anti-UN mig 29s, these migs carried the sword-cross emblem. the dog-fight last about 1 or 2 minutes, and the screen time for the migs, I think, is less than 1 min
a while ago, Hasegawa release a limited version of these mig 29s, it was in 1/72 though.

edit: the base kit is Academy Mig 29 1/48, decal from authentic deals, and the sword-cross emblem was a special order from Samueldecal. the figures mostly from Hasegawa set, the pilot was CMK resin
