While they are named for the Age of War era formation, the Tikonov Guards are an entirely new formation. There are four augmented regiments, raised from pro-Capellan insurgents and defecting RAF planetary guard units from across Prefectures IV, V, and VI. They were equipped initially with both stolen RAF equipment and 'Mechs supplied by the CCAF. Following their reorganization, they have preferred to use Tikonov-built designs like the Kosheci, Thunderbolt and Cataphract in their ranks.
Their units are painted Dark Green and Goldenrod. I suspect this scheme is based on the MWDA Liao miniatures.
The 2nd Tikonov is the most gratutiously Soviet-flavoured unit I can think of in CBT history. I love it.
