Ukrainian communities in the US have collected funds to buy armor for Ukrainians involved in the conflict with Russia. I don't know if only money was supposed to be sent over, or there were ways to piggybag a purchased armor onto the official military aid that US has provided to Ukraine. I don't know what happened at the end, but I surely know that my friends, who are/were local Ukrainian community activists, have asked me what to/how to about the armor explicitly for the above reason.
