Also ofc a lot of these soviet era weapons still are effective solution.
These RPG-7 and USSR era anti tank mines etc etc.
Machine gun with 7,62x54 mm ammo isn't lesser effective than with 7,62x51 mm ammo etc etc.
Btw 7,62x54 mm ammo is really notable cos if manufacturing quality was good and storage conditions good....then even after >60 years cartridge will work.
