I do not think there is an advantage to the attacker, irrespectively of the means of each. For what I am getting in interviews the RF does advance, but the cost in lives is very high. Basically they are sending "human decoys" to "detect" Ukrainian positions. Ukraine would have left the place if they felt it was not the right place.

I am going to leave to you to think why have they decided that it is the right place. Why are they there, why are they holding the place and what they may be waiting for. You do not need to be a genius to answer that.

As side note, the range of HIMARS means they do not have to be "there".

Meanwhile, the RF air force has decided that it is ok to down US drones in international waters. I wonder what may happen next.
