That looks like it is good or large concentrations of troops/light armor etc. Curious how that will work with trenches.
Not as well as the folks in here who are getting all moist talking about them would suggest. They're specifically designed to kill/main troops and vehicles out in the open where there is no cover for people/vehicles, which means the disadvantage of having small amount of explosive within each submunition (only a little more than a hand grenade in the M42/M46 used in DPICM) is neutralised by having lots of those submunitions all simultaneously explode with nowhere to hide from all that shrapnel.
However, with trenches and dug-in troops there's lots of cover, and now the small amount of explosive within each submunition remains a disadvantage and even if any submunition is lucky enough to land in a trench, its shrapnel spread is limited only a few meters before the trench zig/zags, specifically to prevent shrapnel flying down it, something we learned to do over one hundred years ago and still relevant today.
Instead, for troops in trenches you use lots of 122/150/155/203mm artillery firing a mix of airburst (at about 20m/75ft height) and delay fuse - airburst to hit anyone exposed in the trench who is trying to observe or shoot at your troops (155mm airburst shrapnel range is 200m+ at 75ft height), and then you need delay fuse to dig out strongpoints/bunkers, physically wreck the trench walls, rip up barbed wire/obstacles/mines etc. So airburst to kill/main and delay fuse to destroy infrastructure/barriers.
Again, none of that has changed since WW2 when an accurate airburst radar-based fuse became available which could be set for a certain consistent height rather than the older WW1 timer based ones which made airburst very unreliable.
Just a point of clarity too, despite what wikipedia said and it's 100% wrong in this case (I've tried to change it, we'll see if it stays) neither M42 nor M46 submunition has an "airburst" capability which is what the Wiki page for DPICM suggested (if my edit doesn't stay). At best it could be trying to describe what happens when a submunition hits a vehicle roof and detonates at head height, but it is certainly not "airburst" as both of these are contact/impact detonated submunitions so they have to hit something solid to go boom, but then again since when has Wiki been an accurate source to use

I've maybe seen 1 poster say they enjoyed seeing Russians die.
I would suggest you look again, but I doubt you will, not through malice etc but just due to the sheer amount of posts in here now making it almost impossible to search through. However, I know with 100% certainty that there's easily over a dozen posts from people who've openly said they wanted Russian POW's murdered (after the 1st castration vid), all 140 million Russian men, women and children killed, even Serbia to be invaded and wiped of the map killing another 7m all because the poster "thought" Serbia supported Russia etc etc, most of which I quoted.
If you wish to believe that only 1 poster in here gets excited by seeing drone footage of Russians dying, I would suggest you are very, very naive to put in kindly.
