This was textbook Des Moines (USN CA) gameplay. You either get aggressive early and blunt the enemy advantage or go back to port in shame. I'm surprised by those claiming someone with ~305k damage in a Des Moines as being undeserved... Anyone involved in any gaming military title understands when The One True God favors someone over themselves; in this case, our hero in the Des Moines. Especially a Des Moine running Range Mod.
A few years ago I would call this undeserved. Guy could have and should have died three or four times. But honestly with today's playerbase? Can't say I'm surprised.
