Well you said Ukraine doesn't have enough HiMARS in one place to overwhelm and now you say not enough air defenses to defend a bridge so which is it? HiMARS/M270 GMLRS are very hard to detect with their small RCS and terminal speed of over mach 1 plus. They don't fly a ballistic trajectory they actually maneuver during incoming.
How many of these have taken out weapons depots to the point it causes that nation to look to other "friendly nations" for ammo? How many CCHQ and communication stations has these UAV's taken out compared to GMLRS? There is no comparison.
Static tank you mean. Anything that is static can be taken out by satellite guided weapons if it stays static in one location long enough to be targeted. There are plenty videos of HiMARS taking out all types of armored vehicles.
Russian MOD had claims everyday for the last months since summer or so, about multiple HIMARS shells intercepted. And that's everyday. There are also regular interceptions of other MLRS, all supersonic and with small rocket body RCS. Since HIMARS are launched in three salvoes from three launchers, I would expect at least 18 missiles, and more if Grads are thrown in to distract defenses. However in one such famous attack on one bridge, there are only three hits. I would assume the rest are intercepted.
Buks are also meant to take out tactical missiles so Mach 1 terminal speed doesn't impress. If you are traveling very fast, the faster you go the greater is your Doppler effect and radars take advantage of that.
As for HQs and ammo depots, Russian MoD also officially claims these are being hit and destroyed everyday. Not one, but at a rate of three to six or more, and like wise with ammo depots separately. Certainly enough to cause Zelensky to keep begging for weapons. Many of those depot hits include stored HIMARS shells.
There is certainly no lack of videos of UAVs taking out all sorts of targets. This includes the barracks of one Ukrainian brigade. Not to repost pics or videos that are already posted.
Somehow you keep thinking Shahed when another UAV, the Lancet can take out repositioned targets.
The Krasnopol MLRS happens to be laser guided. Seen enough Russian videos of vehicles being taken out in one shot while they are still moving.
