"If the tank is" IP-4 "has been established gun C-70, then the player gets a new IP-4 with an established tool of 122 mm," M62-T2 ", otherwise the player gets a new IP-4 with a tool set" D25-T »", which means you need to have S-70 gun on Tier9 IS-4 to get the 122mm M62-T2 gun on new Tier10 IS-4, otherwise you can only get a new IS-4 with 122mm D25-T (stock gun).
this could mean that is4 will have 2 guns, D25T as stock and M62-T as researchable like E100
