Couple of videos I hadn't seen before on the Boirault No.1 and No.2 Barbed wire crushing devices.
The massive exposed drive chains on the No.1 device beside the drivers would give a modern occupational safety officer a coronary.
The No.2 device looks as if it was modified to tow a ramp. It could have been an attempt to create a bridge layer for tanks
to cross rivers. The St-Chamond tank didn't seem to have enough torque to climb the ramp though.
