The Viggen is a unique beast in DCS at present—the only radar-equipped ground-attack plane at the moment, and the MiG-21's A-G counterpart in that its mission profile is highly preplanned. The upshot is that sorties are short and focused. It isn't a terribly hard plane to learn, although the HUD symbology is different from everything else. That said, I'm all for one thing at a time in DCS.
My dynamic campaign hasn't been going too hot. My first mission saw me sent a short-range SAM site. I took rockets, given that the weather was terrible and I didn't think I'd have the time to line up a Maverick shot. The weather was worse than I thought, though. As soon as my wheels left the runway, I was into the cloud layer. While flailing around in the clouds trying to aim rockets at the waypoint dot without crashing, the SA-8 plugged me with a pair of missiles.
Next up, I was assigned the SEAD role: jammer pod, chaff pod, and Mavericks. As I was leaving the airfield, on my way from it to the point where I was supposed to meet my escorts, I got nailed by a passing Su-25, who, rather ironically, had just finished blowing up the local SAM battery. (Thanks, guys.)
Tonight (potentially): a night attack on fuel tanks at a harbor. I can hardly wait to see what new modes of failure I get to experience.
