Eastern European crisis is a mod telling a story about the future of Europe. In 30's of XXI century, NATO power weakens, European economy deteriotates and ethnic tensions inside such countries as France, Britain and Germany rises. In this situation, Poland and Ukraine become once again one of the biggest economies, because of these countries stability and large deposits of shale gas, which boost their economic abilities.
The Rosomak is Poland's workhorse for carrying troops over the field. Designed after Patria AMV APC in the beginning of 21st century, the Rosomak is not as advanced today (2020's) as it was 10 years ago, but still more than a match for Ukrainian trucks and BTR-3.
Unlike BTR-3, Rosomak has no anti-armor weaponry, but armored significantly better.
