Really bad, just because its a B movie and made on the cheap doesn't excuse how bad it is. Most action sequences are in the same bit of wood with the same line of trees. We only see the top of the factory in wide shots. How did the Captain know there was an old abandoned church when he was behind enemy lines and had not done any recon. Who thought they could pass an early 20th Century style middle American church off as an old European one. That might pass in America but it would hit any European in the face straight away! There is the sequence where you can see the squibs exploding in the dirt. The time line is ambiguous and I know there are flashbacks but they don't fit properly, and who could possible forget the night of the landings! Why did they say that, show the flashback and say it again? I think the biggest problem was just careless editing and no attention to detail, and I don't mean the authenticity of weapons and uniforms, if the film is good enough you don't notice that. But if you are bored enough you will look out for faults. Oh yeah and why, in the graveyard battle sequence, was there are truck in wide shots but close-up shots were of an armoured car that hadn't driven on to the battlefield - when they ran into the clearing there was only the field gun so where did it come from?
