Russian Army leaders and Guards units

[Poor Yorek]

   Rich,
      Your interpretation is correct, Guards leaders can direct both Guard and Army units. Army leaders may only direct Army units. If the rule is not in there in should be. Thanks, Mike 
  

So the same would apply to Kommissars? Not at home to check on Guards vs. Army Kommissars - the question just occurred.  

I could see a Guards sergeant laughing at an Army Kommissar holding a pistol directing the former back to the front.  "Your proletariat bullets mean nothing to a New Soviet Man."
