I played your mission for about an hour, had a lot of fun. Setting the minefields was pretty easy. At one point I drove the mine carrying halftrack a little further down the road to set up mines further away, it worked very well (assuming your engineers are still alive). I was able to get both engineers working on laying mines at the same time, which I thought was good. It seemed like all the incoming German vehicles spotted the mines though because I never saw any of them run over one.
The best part was when a German halftrack pulled up next to me and sat there. I was able to walk up to the rear of it, open the doors, and shoot the two crewmembers inside.
Both of my Soldiers with the Panzershrecks couldn't hit the broad side of a battleship with their rockets, although they did have some luck with the RPG-40 grenades.
The game worked very well for me, no issues with the scenario or the game for that matter.
