Victory for the weary Wehrmacht! After a short, yet intense, firefight, the Germans manage to earn a rather lopsided victory.
Germans: 8 casualties (6 KIA, 2 WIA). 3 AFVs destroyed (all Pumas).
US: Approx. 60 casualties (20+ killed, around 40 WIA). 10+ vehicles destroyed, Greyhounds and jeeps.
As it turned out, I didn't need a very detailed plan to stop the Americans. I kept the Pumas you get in the beginning exactly where they spawn (which gives them a chance to get some flank shots against US armor advancing on the single-lane road).
Once the German reinforcements start trickling in, I tried to get them into the best firing positions I could find (which was more of a trial and error thing) and kept blasting away at the Americans. I got two infantry guns as well, but never had a chance to use them. The Pumas did all the hard work.
On the American side, the only real danger was posed by the Greyhounds + American light mortars which managed to immobilize two of my Pumas.
I didn't have enough infantry (only four guys, one of which got killed approaching the houses in the middle) at all to properly support the Pumas, but everything worked out in the end for the Germans. The Americans asked for a ceasefire, after 15-20 minutes.
