UA Georgian National Legion. Some info:
The unit has been acitvely engaged in Ukraine since 2014 and was originaly made up of mostly Georgian but also a minority of American and British volunteers, including women who served in the GDF, and various special forces. They assist the UA in conducting combat patrols, ambushes, and the training of volunteers.
At this point, the Legion has grown considerably as it has been taking in many more foreigners since the invasion.
In fact, so many volunteer from as far as India and Mexico, have applied for Georgian Legion service, that they had to suspend recruitment, just to catch up. The Legion doesn't take everyone. Many people were refused. Except for medical personnel, they expect people to fight wherever called to, and if needed lay down their lives in the defense of the country.
