I wholeheartedly recommend reading every single one of the texts archived at the MIA about the Black Panthers, specially for USians. They’re the most didactic and practical ountraslated English-language texts one can find on communist activity, with the added benefit of countering effortlessly the whitewashed narrative of the 60s to the 80s of the US most people learn in school (both in the USA and abroad).

You can also listen to interviews and speeches from Huey or Bobby Seale (sadly I couldn’t find much in audio from Fred Hampton).
