Heavy Tank-Men

People given 4 strength activations are known as Heavy Tank-Men, and have a much greater amount of strength, alongside large amounts of height and weight, but at the cost of the halo effect, making them defenseless at range. In addition their bodies are supporting such large amounts of weight, that the tearing of 1 ligament in their knee can result in them being unable to walk. This was first used by the allies during the raids on the Hamburg U-boat fortresses.
