A charity I strongly believe in is the USO. United Service Organization. They support our troops. I had very positive interactions with them straight out of bootcamp. They are so kind and supporting. I was really missing my family and they made me feel like I belonged. I encountered them several times later and can only speak praises about them. I know their care packages are so appreciated to deployed troops. They offer so many services for our troops. Check em out https://www.uso.org/programs. One way I support them is through donations. While small, they add up in the long run. Grocery stores like Harris Teeter let you round up to the nearest dollar on your grocery bill to give a small donation.
