Artillery crews would build defenses for their guns just as infantry would. Logs, earth and sandbags would be used to create positions where the guns could be manned in relative safety. These kits provide twelve 15mm gun pits, eighteen 10-12mm gun pits, twelve 20mm gun pits or nine 28mm gun pits. The pits come with three different kinds: a large pit, a small pit with a narrow front and a small pit with a wide front.
