In 1969 campaign, after the mission in which i have to defend the base against VC tanks and infantry, it says that I've failed the campagin. After that I can see the cinematic in which I've been transported to USS Enterprise (or Nimitz?), and after that I got this message: Campaign Failed. Is it suppose to be that way? I've played this "defend" mission for 10 times, each time killing nearly 20 vc's and destroying 2-3 tanks, and still it turns out that way.
