Example fourth hospital: the Hospital (HQ 21) needs the research “Extra Hospital” (Defense Fortifications, Tech Center 20, 250 VS medals, 6.23M food/iron, 18.7M coin, 2d 19h 23m), which needs Special Forces at 40 %. Pick “Special Forces” and 40 % above: cheapest way is 89 of 221 levels, at least 49,160 VS medals, 546M food and iron each, 1.64B coin, about 200 days base time, Tech Center 22. Assumption: 40 % = 40 % of all levels in the category.
