"A highly specialized operative team consisting out of US G.R.A.N.D. Spec-Ops and Troops of a still unknown source were assaulting a California Mountains villa. The villa was confirmed to be a hideout of the last remaining Warsaw Pact Officer on American soil as well as a small group of Russian Spetsnaz defending him. After surrounding the fairly rundown villa as well as taking positions on nearby hills and mountains, the actual operation did only last a little bit longer than half an hour. Operation Aftermath is considered to be the end of the fight against the Warsaw Pact in America, as that it also determines the failure of the Warsaw Pact´s attack in 2028."
Based on this Halo Concept Art. What I think is funny is that I actually even (unintentionally) entirely copied the weapons and where what figure with what kind of weapon stands, but with modern weapons of course.
