Yes, for example, there are three records of lieutenant general Ivan Nikolaevich Muzychenko as missing in action in August 1941. Who was actually repatriated to the USSR and lived until 1970.

So 3 records - 1 person - 0 casualties.
Unless you have 1-1-1 correspondence these numbers don't mean a thing.
I'm not really sure where 14 million came from. My count yields about 11 million records in lists of casualties.
