I played a bunch of it in the late 80's...
It plays well, it's fast and easy. Well, as fast an easy as counters on map ever gets.
I preferred the AP system from Snapshot, and used striker as my baseline rather than AHL, because there's more of the weapons list there. Striker and AHL are 99% compatible... and the weapons tables are 100% compatible.
It's actually a bit more brutal than Bk1 combat. In practice, it's also slightly more so than MT, because the DGP guys use the same armor ratings and pens in MT, but the relationship to armor is buggered.
(In striker, you can pen armor of AV ≤ Pen+8 and fail to penetrate AV ≥ pen +3; in MT, you fail to penetrate AV ≤ pen -1...)
