Gameplay video posted by TaktOPAirsoft of Op Thunderdome 5. The retro "Oil War" themed Operation Thunderdome V, hosted by Lion Claws, saw US forces triumph over their USSR counterparts for the first time in four matches last March. This victory marked a turning point for the US/Tan faction, raising questions about their potential for continued success and whether the traditional powerhouse USSR/Green would be able to reclaim their dominance.
