I dunno, I would have swapped a lot of army officers for some of the firsties I met at West Point in a heartbeat. Not the ones in leadership among the cadets, mind - they were utter rubbish. The more junior cadets, also no, but that's not what Russia is doing.
Now, considering that these are Russia's equivalent of Army Corps of Engineers cadets, it looks less like a good idea. Your point about giving them the impossible job of handling green conscripts is also well-taken.
I may not have alluded to it correctly, but junior cadets have the enthusiasm and optimism of youth; look at the Hitler-Jugend as what can be achieved.
So I appreciate that point. Yet, this is a more complicated issue as at first Russian officers are in general not effective as many of their western counterparts.
There's also the huge element of the inexperience and inefficiencies of NCO cadre. When officers leave Sandhurst, Cranwell or Dartmouth, they get support.
The senior NCOs (Sgts, Colour/Staff Sgts and WOs, and even Cpls.) can and do provide advice based on many, many years of experience and training.
The notorious lack of leadership within the Russian army, with NCOs often having a mere few years of experience, if that, will mean it'll be the blind leading the blind.
Discipline will be lacking, experience may be non-existent, and this may result in an unwillingness to fight. Can you see these units standing and holding the line?
