Mostly I do google searches on current hot spots (e.g. Fallujah), looking for news.
I also go to twitter (searching for #Fallujah, and #Manbij for example). That is where I find a lot of very current and detailed info, often from people on site. It is not vetted, so you have to use your judgement, and be aware of bias. There is a contest of opinions there - ISIS fans post their story, Iranian media, Turkish, Kurdish, Russian, etc.
I am retired military, and deployed over there a few times.
