The problems is that every artillery system has its own unique ballistic characteristics, so firing data is unique for each system. Computers take care of some of that, but that means you'd have to train Ukrainian artillery people on how to operate our artillery targeting computers and software. They could compute it all manually without computers, but the manual stuff is all in English and also would have to be learned. So this isn't going to be a lot of help in the short term.
Which if we had competent people at the helm would have been done in January at the latest. (We knew the invasion was coming, says Blinken.)
Manual operation is slow, though. Good way to get yourself killed, in 2022. Get those 19 year old Ukes on simulators yesterday.
