Got the game for Christmas, playing as Japanese player vs. AI.
Want to make sure I understand this (please correct me if wrong):
1) To repair LI, HI, plane factories, engines factories, naval yard, merch. yard, repair yard, vech. factory, armament factory, manpower, resources, oil production, and oil refineries it costs 1,000 supplies and takes one day for each repaired.
2) For #1 to occur base must have 10,000 supplies or more.
3) For engine R&D and plane R&D factories (unrealistic R&D) does it cost supplies to repair?
