Soviet military traditionally relied much more on commissioned officers serving in roles which would be filled by NCOs in western militaries. This probably engendered a greater tendency and habit for commissioned officers to lead from the front than might be the case in western militaries.
In addition, the tactical defects the Russian army appear to exhibits could perhaps also be attributed to shortage of highly experienced NCOs leading soldiers at the front. If these gaps are partially filled by relatively inexperienced junior commissioned officers just out of military academies, that might explain such symptoms as tanks advancing in tight columns down unsecured urban streets. If lower level leadership are inexperienced, than that put more pressure for field officers to keep tighter watch and frequently visit on front line units to make sure they know what they are doing. This may reflect all the way up the chain to general officers, leading to excess general officer casualties.
