This is the command structure under which the volunteer served. https://en.m.wikipedia.org/wiki/114th_Territorial_Defense_Brigade_(Ukraine)
There is one specific company I found raising funds separately for the brigade the US volunteer was in. The team is here https://sigma.software/about/management-team
They show fund raising for a separate reconnaissance unit of the 135th Territorial Defense Battalion but the link is bad here and points to the 40th…They claim “19 of our colleagues joined the ranks of the Armed Forces of Ukraine and territorial defence in the Vugledar, Bakhmut, Mykolaiv, Donetsk, Kharkiv, Kyiv, and Chernihiv directions.” https://unity.sigma.software/en/
I have been donating to UNITED24 primarily because I didn’t want funds misdirected. They have these contact emails. If someone in the business wanted to ship some units I think the Brigade level or the UA24 contacted directly might be the most direct contact for coordination.
