In keeping with today's canine theme... from the UK's TimesOnline:
Dropping from 10,000ft, they glide in order to land unnoticed. The dogs often carry cameras and are trained to attack anyone carrying a weapon.
“Dogs don’t perceive height difference, so that doesn’t worry them. They’re more likely to be bothered by the roar of the engines, but once we’re on the way down, that doesn’t matter and they just enjoy the view,” said the dog handler. “It’s something he does a lot. He has a much cooler head than most recruits.”
Commandos from 14 countries, including British special forces and Royal Marines, took part in the Nato exercise. The use of dogs in High Altitude High Opening missions was pioneered by America’s Delta Force, which trained the animals to breathe through oxygen masks during the jump.
