That OP is twisting this as hard as they can, into a show of 'Ukrainian weakness'. Apparently, deploying a new battle technique can be slammed as desperate.
The mindset of the article is old-fashion.
It labels the use of RC as a sign of weakness -- as if sending soldiers which end up as casualties is a sign of strength.
The Ukrainians won that battle with significant less human loss and cheap tech. That's all that counts tactically?
