Five hundred AK74s plus two million 5.45mm caliber bullets only cost seven hundred thousand US dollars, and for AK47 bullets, Gao Yang and his group initially wanted ten million rounds, but Uriyangko didn't have nearly that many. He gathered Russian, Huaxia, and Eastern European ones and barely managed to scrape together four million rounds.
The total cost for four million 7.62mm caliber bullets was also just three hundred thousand US dollars. These bullets produced during the Cold War era are now outdated for those major powers, but they still have a huge surplus, and military surplus ammunition is that cheap.
Two hundred RPG launchers plus ten thousand various types of rockets needed six hundred thousand US dollars, one-time use RPG-26s cost three hundred thousand for a thousand units, ten '63 model 107mm rocket launchers along with rockets exactly one million US dollars, and forty thousand hand grenades two hundred thousand US dollars.
