There was a German using a PPSh-41, another with a '42. One of the guys in our unit was using a "captured" SVT-40. We also brought a MG-42 and a grenatenwerfer. Some guys I. The other German unit were using some MP-40's, one had a K98k with a scope (which was pointless due to the weather, terrain, and foliage). There was a wide range of weapons used.
The event, numbers wise, was about 50 people. Perfect for a small skirmish in swampy, mucky, muddy, brushy, hilly, wet land. It was HARD moving around in the terrain, especially for me being overweight, but it was still great.
