After hiking for 45 days, Marine veteran Ramon Castro is reportedly nearing the end of a 2,000-mile trek along the U.S.-Mexico border to protest the deportation of noncitizen veterans. Over the past two decades, thousands of noncitizens enlisted in the U.S. military, providing critical contributions to operations in Afghanistan, Iraq and elsewhere. Despite their service, the U.S. government deported perhaps thousands of these veterans from the nation they fought to defend.
It’s hard to know the exact numbers: in 2019, the Government Accountability Office found that Immigration and Customs Enforcement (ICE) didn’t consistently keep records of the numbers of veterans it deported — and didn’t consistently follow special procedures it had established for veterans facing removal.

Although research on foreign legions and the states that recruit them is still growing, recent history suggests lessons and insights that seem tailor-made to inform Ukraine and those following its conflict closely. In particular, Finland’s use of legionnaires during the Winter War suggests how these volunteers not only provide a boost to the combat effort, but can also serve to rally the international community.
