Boomer was Typhoon class submarine. The one that tried to spoil the party was an Alpha and it was the one everyone was worried about with the titanium hull. Soviets were never able to get it to really work right, but it helped many an Admiral pad their capital and development budgets.

In RSR, the Russian generals talked about their attacks getting bogged down by light missile crews and how they had underestimated their effectiveness. Glad ol' Putin glossed over that chapter.

It's also interesting how in RSR the Russian offensive ultimately came down to logistical, specifically fuel, support. Art imitating life.
