But they will eventually have to switch to more advanced ERAs especially with the planned introduction of the T-95 in the next following years. If they are reluctant to upgrade their production lines at present then the new T-95 might as well end up using the old K-5.Of course it's money. In serial production Relikt won't be more expensive then K-5, but retooling the factory will cost some millions which nobody wants to spend.
That's war how we used to know...
i love these gasmasks! They look really scary.
