Two very good and one reasonably good films in one. It feels undeveloped for the most part, especially during its middle Vietnam section, but it's a well performed crime / war thriller with a particularly marvellous turn by the always terrific Keith David.
Structurally similar to Goodfellas but I actually liked it more-it's more engaging throughout and is, I think, incisive and angry enough to warrant some compelling discussion. I think it should be more highly regarded than it is. It certainly beats the living piss out of "Carlito's Way."
