The Vietnam DLC is my favorite so far. Love flying the Huey.
Being able to play a bunch of former aces high players who are not right in the head makes it even better.
Staying with the WW2 sims, I had more than enough of lovely Vietnam in 1967/1968 to fulfill my lifes experience of Asia
.
BUT, as you I do love the Hueys coming from an Air Mobile brigade and dozens of air assaults in the birds.
