Happy to be corrected but I think this isn't 100% true, the only 'news' site I could find reporting it was very dubious and tried to install malware on my computer.
Plenty of sites (https://goo.gl/yFWxWe) with this soldier's name describing his heroism, although, as you'd expect, they are mostly Filipino sites, as he was Filipino. And he wasn't fighting ISIS, per se, but a terror group in the Philippines with connections to ISIS.
This will have given his life meaning. Respect.
