Pretty good Dar there Roman,i enjoyed the read
As a suggestion,if you don't want go with the Aluetions again,you could set next battle or two with one VH near the JIA and after repairing simply deploy your force to the edge your map side and retreat.
You will lose,a battle or two, but still gain some exp.and get out the boggy Aluetions,to more firmer ground where armour and transport might be more effective in the South Pacific.
Whatever you decide,Good luck to you!
