As a NATO officer with over 20 years of service, I can tell you that most of our training was informal (or Collective as we called it). See slide #7 here http://jarche.com/2010/12/getting-to-working-smarter/ It was run by Operations Staff, not the Training Branch. The military understands the value of informal learning, such as after intense operations - http://jarche.com/2006/07/learning-through-storytelling-with-the-ppcli/
