X-Terrain expansion sets add 3-D buildings and fortifications to Sergeants Miniatures Game. While buildings and other terrain printed on the squares and landmarks of the Sergeants map provide some concealment, but little or no protection; X-Terrain adds critical points of elevation — allowing the soldiers to climb — and introduces true line of sight rules. Many of the locations also protect against hits scored during battle – either because of wood, stone, concrete walls or because the soldiers are dug-in.

These 3-D structures are created from the same durable material as the map terrain tiles. Each piece is easy to construct and with proper care, are made to last. Also included are scenarios, orders, and special equipment that will work with a variety of SMG starter sets and expansions.
