Prior to a major military offensive there will invariably be probing and shaping attacks.
Probing obviously being testing for weak points. Shaping amounts to attempts at confusing the enemy, perhaps getting him to move resources to meet perceived threats which are actually feints. Leaving the real avenues of attack weakened.
Virtually since day one in here team Russia have been reacting to these activities with "HUGE losses" and "The total failure of the Ukrainian counter offensive" type posts............. Sorry, I forgot to add the usual ..................
Whether the Ukrainian offensive ultimately gets significant results or ends up a damp squib - just like the chillingly threatened Russian winter offensive - remains to be seen. Much of the above though really amounts to no more than wishful thinking.
I said earlier "the fog of war". It's a pertinent expression.
