Well IIRC, for America, the funding money amount for Ukraine is usually just an estimate of the worth of already manufactured goods, mainly of weapons that we have stored that we weren’t gonna use in the first place, and only a small portion of the dollar amount is stuff like clothes, food, etc. which would be seen as an actual cost to the US. We have sent Bradleys and M1 Abrams (and some European countries sent Leopard 2A4s? and Leclercs I think), but I’m pretty sure they weren’t in use by the military and weren’t planned to be upgraded for use any time soon (but I’m just guessing, I can’t Google it rn, I may just be completely wrong on that).
