Guys, I'm Ukrainian and I want to help my country's defenses, got a network of people abroad that want to donate funds, but I don't know where best to direct them to, which cause: military equipment / medicine / other. I'm reaching out to our local funds but they're overloaded rn so might take a while to respond.
Does anyone have experience with the efficiency of donations in the times of war?
Can you point me to the right people / literature?
Thank you!

thank you @dpiepgrass! the point about spreading out instead of focusing money on the same orgs makes a lot of sense, I've made my company do just that and I'm spreading out my money as well.
another thing I hope I can help my people with is spreading information and generating as much support from other countries as possible
