Ostwind
We’ve made some significant improvements to the Ostwind to improve its viability over the Panzer IV which was generally chosen as the first tank for Ostheer thanks to its ability to fight both infantry and medium tanks. Its ability to destroy infantry and aircraft at a lower cost compared to the Panzer IV will allow it to find a place against certain builds.
