Unfortunately I have no seen Chechen Wars. Then I lived in Israel before coming back. I can give you an example from my Middle East expirience however. It was at autumn 2000, just after Second intifada started. The FATH or Tanzim fighters attacked our outpost at the road Jerusalem-Gush-Etzion and cut-off the traffic between the capital and the Jewish settlements southern of it. That time I was mobilized in 'miluim' (the Israeli reservist sevice) as a "medical officer" or military doctor if you want and my little unit provided med. help for events at this road and Bethlehem checkpoint simultaneousely. I had the paramedic (woman), 7 or 8 nurse (only two between them were men) and two transports. So, with these forces I had to garantee medical help for the wounded Israeli soldiers and if need for captured and civiliance too, but OK listen further... We received the call with information about two wounded, but our group waited 2 hours till the sniper duel at the point was over. During this time one of the wounded died from the bleeding. I still speak about super 'lucky' situation, good roads, short distances, mobilized infrastructure.
Other part of my annually service in reserve were exersises with the medical company of an Israeli tank division. Yes, we had the higly trained evacuation teams with the vehicles, though the evacuation from the battlefield remain the crucial point in all this calculation. However the first 'gold hour ' is a decisive time for the seriousely (but not lethal) wounded, and it can be problematic. I understand that it's may be very important psychologically to be sure for the soldiers the medical help is ensured, but if realistically thinking the effectiveness of all these measures in a big war is diminished. If the evacuation cannot enter battlefield during 2-3 hours (what I expect in the worse scenario), the medical help has only limited point.
Coming back to our topic: the blow-up panels reduce the number of killed but can rise the number of wounded and shoked (due to superficial placement of the rounds and their bigger vulnerability). Thus their effectivenes as a 'life saver' is depended of the medical help quality and early evacuation. And I can find you number of tactical scenarios where the life expectance of the survived ammo blow-up tankmen is short.
