Terrain supplied with the Skirmish Battle sets was by necessity basic and with no frills. But they were effective and not produced without some thought. Here are the pieces, which can be assembled handed or reversed, or simply mixed up if that's what you really like to do.Heck it's your game too!!
The Parabolica This was a simple piece of terrain in the form of a rocky outcrop with a parabolic opening, with a compound of cover at it's front.
The Fissure This was an even more simple piece of terrain in which one or possibly two figures could take cover in the Rocky fissure.
