What's up with kelly, Linda's, and Fred's Mark VI armor sets from Halo Escalation? We now know that Fred's armor is the centurion variant, but Kelly and Linda's armor sets are kinda bugging me because the overall body armor looks similar to John's Mark VI custom (his halo 4/ Halo 5 armor). Are they based on old Mark IV variants? Does this also make the Centurion armor from H2A a prototype of the GEN. 2 version that's seen in Escalation and Halo 5 Guardians?
