@Mallekip Thanks for the kind words. I can offer some advice to get the most out of the mission:
- Use rockets against soft targets, and the Vulcan against hard targets.
- Enemy vehicles need not be destroyed, but disabled.
- You'll only lose when the first enemy reaches the red line.
Keeping that in mind, prioritize! If a new push spawns closer to Khe Sanh, shift your focus and come back later.

The current wave cooldown for SP is set at 4-7 minutes, which was a rough estimate for an optimal value. I'll consider extending it in the next update.

Now, the co-pilot gunner.
Given the anti-tank nature of the mission, the weapons available to him truly are of mostly decorative value. In my experience, ordering him to use the 40mm cannon yields better results (Ctrl+F by default), but really, it's only a small dent compared to your 20mm Vulcan.

Hope this helps you or another player get the most out of it!

Thank you for the update. It's a lot more polished, and the addition of some anti air fire near the convoys make it more dynamic.

However, I'm not quite convinced by the AI gunner/copilot. I couldn't get mine to fire anything but the MG and the smallest rockets. It took about 100 to kill a single tank. Not very efficient. So I ended up using manual fire regardless.

Also the frequency of new convoys has increased to well beyond what I (an ok pilot who doesn't do flips on KOTH) can handle. So for the players: bear in mind this is quite challenging.

This mission has gotten a significant update on June 3rd. It's been tested in SP and MP but there's always a chance for bugs or balance issues.
