Brigade Models has released their new 15mm Turret Bunker terrain piece over in their webshop.
From the release:
Today we’ve added a new model to the Fortifications section of the 15mm range. This is a heavy bunker fitted with a tank turret to make a powerful strongpoint for any defence line. The bunker has a number of turret options – just about any tank turret from our 15mm range will fit, giving you plenty of choice. All versions retail at £9.00.
