The Soviet (Russians) had a different identification method in WW2, somehow unique – a bakelite capsule contains a form that the missing soldier had to fill in active duty: full name, date of birth, place of call-up and other kind of information.
Sometimes it wasn’t a standard form but a piece of paper that the soldier got somewhere and filled in as he himself wanted. The standard capsule was provided by the Soviet (Russian) army.
Opening a medallion find near the missing soldier is always an anxious thing because there are not very well preserved in time and any careless movement can ruin a form.
The containers showed in this video were recovered recently – find near the remains of two unknown soldiers.
