I have some military-grade gear from my time in the army that would be useful for anyone sitting in cold, wet conditions, and that has to move a lot. For example a soldier. Can anyone here give me an indication as to how it is best to send it, and what is needed most? How can I ensure that it gets to the people that need it?
The easiest and most reliable way is via the Ukrainian volunteer communities of your country. The organizations which collect and transport donated things act in a transparent and responsible way, providing you with photos from the receiving party.
In the UK, for example, it’s https://www.british-ukrainianaid.org
In the US - https://ukraineaidops.org/ and other orgs.
