Wagner has 50,000 soldiers. Only the infantry jumping into trenches are ex-prisoners who serve 6 months for a pardon. The officers and skilled positions are ex-military from around the world but mostly Russia. This man being interviewed is not an ex-prisoner, most likely an officer.
An Australian Army officer said the Wagner Group has the latest tech. Night vision goggles, electronic soldier ID. This lets them know who is a Russian soldier so at night thermal imaging revels two groups of soldiers (i.e. bodies at 98.6 degrees F). They see one group as ours and the other as not ours. They have exact co-ordinates for artillery.
