The picture becomes a little strange when you see the one guy has a walking stick, and the other has a zimmer frame... and they look to be in their mid-thirties. Are they injured vets?
Looks this way. Young (18-20 y/o) soldiers who fought in the Chechen war in the year 2000 would be now about 31-33 years old.
Not necessarily strange - maybe from crashes. I would speculate that those guys routinely run long distances on unpaved roads that are a little more challenging than the US standard superslab. What they call leathers looks more like body armor - there’s a clue.
