The "What if?" skin of Lt.Quang aka "Halo 11" , a cut character from AC7's VR Mod.
The existence of Lt.Quang aka Halo 11 is revealed through the data of unused VR missions. According to the data this character has a significant role in VR mode alongside Omega 11, Viper 2 and the main character, Mobius 1. The idea of the skin is since the character's name is in Vietnamese so it makes sense to give him an Su-30M2 coupled with VPAF skin.
Trivia fact : VPAF is using Su-30MK2V, which is a variant derived from the M2
Replace skin#2 of Su-30M2. The zip file also includes the emblem of Halo Squadron (fanon)
