Custer would have done just fine...
... if he had the air support to wipe out 90% of the opposition like Mel's gang did.
In these days of different demographics, there aren't so many surplus working age men in the USA; I think we should focus, as we are, more on obliterating the enemy from the skies and less on having our cannon fodder battle mano a mano with theirs.
Let's not ever ever enter a fight we aren't certain we're going to win. Fewer Col Custers; more air bombardment makes good sense.
