Whether it’s Excalibur or not, they’re certainly are using something…
In the meantime the news is depressing. Listening to the BBC UKR podcast this morning the Russians have a 20:1 advantage in artillery in the Donbas and a 40:1 advantage in ammunition and are making it tell. They are also getting their act together in EW against commercial drones, I don’t know how many Starlink equipped/secure comms drones they have to replace them.
This seems to be developing into a war of attrition where we see if Russia will run out of troops and trucks before they can break through the UKR lines vs UKR getting their reserves and NATO supplied HIMARS into action in sufficient numbers to hit Russian artillery and supplies.
