Possible to re-use bones/poses in subsequent models?

Is it possible to re-use bones and poses created for one model with subsequent models that you create? Thanks!

yes. Make a copy of your armature. Parent the new model to that copy & do the weight painting.

Are there any free poses/armitures available anywhere that I can copy and reuse? Specifically combat animations for video games and so forth. I’ve made my own models but want to avoid going through the work of creating all the poses from scratch. Thanks.
