I just got finished reading an interesting book. It's called "Soldier Dogs" by Maria Goodavage and gives a lot of information about where the military gets their dogs, some of the assessments dogs go through to see if their suited for military work and if so, what kind of work. Also, what happens to dogs who don't make the cut, the training of dogs and handlers, war stories and military dogs that make it to retirement age, etc. I never realized that dogs are regarded as "equipment" by the Department of Defense and that many were abandoned in war zones through the years when the US pulled out. Shameful behavior, but hopefully we do better these days...
