Wrapping it up, United Offensive is a fantastic Call of Duty experience that mirrors how the later non-WW2 games of the series would evolve. The action-filled missions can lead to sensory overload when played in long stretches, but going at it in short bursts is the best way to go when tackling the singleplayer.
