Unfortunately the Western equipment is arriving in ‘dumbed down’ condition. Sensitive parts are stripped and sometimes work arounds can be substituted.
Regardless of specs, if old ammo is supplied, then the range is very much reduced. Worse, without dedicated artillery drones, the modern pieces are no more effective than any other piece. Drones are the modern equivalent of FAOs.
What I’m saying is there is no way for long range tubes to correct and adjust their fire. There is no counter to the Orc’s dedicated Orlon 10 with its 5km altitude, 16 hour duration, and 365 mile range. Commercial drones are not anywhere near adequate for artillery.
I guess the have to dumb them down for in case they are captured by the Russians. Maybe some way could be designed to make the howitzer blow up if started without a password. Or perhaps small explosives or other destruct mechanism could be attached to secret parts so they are destroyed if not approached in the approved manner. I understand Russia is having problems trying to use US farm equipment they stole in Ukraine that won’t work unless approached correctly.
