Have they been selling the same Leman Russ model for 30 years?

I've always hated the design for the Leman Russ tank. It looks like a Happy Meal toy. How can a design so ugly last 30 years without a refresh? Surely I'm not the only one who thinks it's ugly, but I never hear anyone asking for a refresh the same way they do for other out dated models. This is ridiculous
