These are the two (high res) representatives from Sandomierz Technology Group (STG), a Polish defense contractor representing Eastern Europe (though many of the components are brought in from neighboring economies). These represent primarily KE resistant designs, though they have solid endurance against all damage being as heavy as they are - with the tradeoff of being slow and somewhat cumbersome.
These were both done by Alec Claravall, one of our 3D artists. He did a great job on these, so if you like them be sure to let him know.
