The ICM 1/35 Dragon's Teeth Anti-Tank Obstacles (ICM35746) is a 1/35 scale set of Höckerhindernisse (Panzerhindernisse) 'Dragon's Teeth' — the concrete pyramid anti-tank obstacles used in the Siegfried Line (Westwall) and other German defensive positions to channel and stop Allied armour. These concrete obstacles are an essential and often-overlooked element of German defensive dioramas, and their distinctive stepped profile makes them immediately recognisable. An important terrain accessory for any Westwall or defensive position diorama.
