|My Germans eye the killing zone between them and safety|
In a nutshell? Brilliant, brilliant set of rules. The reaction rules are what make Operation: Squad, and it's just fantastic.
Here's how it works. Players move alternate figures, so let's suppose German A is making a dash for cover across a street. At this point, the British player can say that Brit X leans out of a window for a potshot at him. The German player can then react to that, and have German NCO B, who's covering A, take a pop at Brit X. And so on, until each side has committed no more than 3 figures. All the figures involved then have an initiative roll-off (2d6 + VT stat): highest goes first, ties are resolved by who declared first, and actions happen in that order. So, if, say, German A rolls 4+4 = 8, German NCO B rolls 8+5, and Brit X rolls 7+4, B goes first and sprays the window with MP40 bullets. If he gets a pinned or better result (wounded, killed), X won't be able to fire back: if he doesn't, X will fire before A makes it to cover...
All in all, elegantly simple and brilliant.
Oh. The battle? The Germans lost, due to getting caught from both sides. But I didn't actually care.
