I am trying to create a US Army Hvy Art Battalion for the 2020 era. But when I go to select the unit for play, I get this message---"No units for this formation is available for this date!" I never encounter this msg when I'm creating other formations and other units in the US Army Orbat. So why can't I create a 203mm offmap Art Bty/Btn for the year 2020?
I managed to get it working! I cloned the right art formation, and edited my copy. When I went to select my formations, no problem---I can now get heavy art battalions---along with the rocket battalions---in the year 2020---just in time for The Invasion of Iran!!!
