UnderAnOpenSky - an addition, because you were interested in weapons effect of GMLRS.
This (twitter, obvs..) is a video of the effects of the M31A1 Alternative Warhead, which instead of a unitary warhead (a 200lb big bang) or the now banned explosive sub-munitions (lots of little bangs), is in effect like a shotgun shell: it detonates above its target, and sends a cone of tungsten balls to its target.
Its designed to destroy unarmoured targets - vehicle parks, aircraft flight lines, radars, fuel dumps, ammunition dumps, logistics hubs, railway infrastructure, troops in the open, gun lines - though in truth it would also fuck up any tank that got in the way...
(Pendant point: though HIMARS tas taken the public imagination, it's only one of three types of GMLRS launcher in service in Ukraine - the UK and German systems fire twice as many rockets, though it's exactly the same rocket, from the same pod, controlled by the same fire control system)
