"Not By Strength But By Guile"

I was reading the chapter in Combat Frogmen about the selection process for the various Special Forces combat swimmers. The training for volunteers of Britain's Special Boat Squadron shows that they are truly an elite group of individuals. The motto of the SBS: "Not by strength but by guile."

The picture above shows a SBS squaddie in dress uniform. The SBS wear the uniform of the Royal Marines. The steely look on his face says it all.
