Great but comes shoret of Perfect.
The game was brilliant compared to the myriad of point & shoot games on the internet, but it had flaws. Now, every positive thing I have to say has been said, so I'll offer some constructive criticism.
1. The soldiers moved too slow, I can understand this to an extent, as I wouldn't be charging through the jungles of Vietnam, I'd take it slow and steady, but in the center of the map, where it's just open ground, I feel strange having my men move at a snails pace. So I would suggest making it so if I double click, it would make my man run, and just clicking would make him move quieter, and maybe give him less of a chance of being shot.
2. This might just be my luck, but it seemed like 70% of the time, my men would be fired upon moments after me starting the game, and if just one man gets hit, it can throw your strategy off by a lot, so I suggest maybe adding a brief period of invulnerability at the start, maybe just 5 or 6 seconds, so I can get my men moving. Yes, it's unrealistic, but some concessions should be made to add to the entertainment.
3. Some of my men seemed really, really, inaccurate. Sometimes my grease gunner would kill a VC from a quarter of the map away, but my sniper would take several shots from a good distance, and miss. I think you should simply make the snipers a bit more accurate, because where some fights could be ended by a single shot, others would take 10+ at a short range with no cover for either soldier.
4. A way to select multiple soldiers would be great, as it was too time consuming to individually select each soldier and give him his orders. A simple drag box would suffice.
5. Most of the time, if I got a specialized soldier, like a SEAL or a Ranger, I'd get just about every other kind of specialist, and if I didn't have a lot of them, I'd have none. Maybe an ability to change the load out (equipment) of your squad, but to avoid having one load out that would rule all, you could change up the enemies and their weapons. (Basically, just do what you did with the U.S. soldiers, in this game.)
6. Lastly, some kind of indicator to show if he's in good cover or not, it was too hard to see if my soldiers were all safe in a heated fire fight. To fix this, just add a little indicator next to men, green for good cover, yellow for okay, and red for out in the open, maybe.
This probably sounded like a lot of things wrong with the game, there wasn't, and you did a great job, but I figured you already know the good things about this game, so I just gave you things to improve on.
P.S. To the guy who said the M16 was perfectly reliable, yes, as a standalone weapon it was, but the Military didn't issue proper cleaning kits for the gun, which led to the misfires and underpowered shots early in the war, so the author is right.
P.P.S. Good Game!
