The United States will send an additional 100 Humvees to Ukraine next month to help the Eastern European country's fighters stave off pro-Russia rebels in the ongoing conflict there. The extra aid was announced June 24 after the first-ever meeting between Defense Secretary Ash Carter and Ukraine Defense Minister Colonel-General Stepan Poltorak. The two, speaking at the NATO Defense Ministerial in Brussels, discussed how to stop Russia's ongoing advances in Eastern Ukraine, according to a news release.
