Impossible Taranov, none of those guys could be Wittmann. Wittmann won his Knights cross at the rank of Untersturmfuhrer in 1942. The guy in the center is already an Obersturmfuhrer (a rank that Wittmann did not reach until 1944), and lacks a knights cross. The only other Panzertruppe there also lacks a knights cross, and has a War Merit cross 1st class, an award Wittmann never won.
