DOSAAF was much more "militarized" than the Young Pioneers, and certainly much more militarized than the Boy Scouts. The name of the organization translated is "voluntary society to support the army, air-force, and fleet". This is a far cry from doing camping trips. I have been intimately involved with some of the draw-down of DOSAAF, and have purchased several airplanes from their former training fleet, including a MiG-15 Fighter that was registered with a civilian Russian registration number and which was used for civilian orientation flying. Piston engine aircraft (Yak-52 mainly) were used to do flight training and conduct aerobatic competitions in Russia, and from these competitions, the best cadets were drawn and sent to military flying schools and entered into one of the three Soviet air-forces (yes they had three different air forces).
Young Pioneers was more like Scouting.
DOSAAF was more like Junior ROTC.
