I ran across this video and found it quite interesting:
And hopefully not offensive since I don't understand a word of it!
I would love to know the historical context of the video from someone familiar with Czech, and also the history of the military there. Some of the photos appear to have been taken in the 1940s (and maybe earlier?) - though I admit I am awful with dates - but some of the dogs have a very familiar looking white mask...
Neat pictures whatever the case!!! Love finding stuff like this!!!
