Eh it is fun to an extent. When I fought with the YPG I saw a lot of Kurds jumping with exuberance cheering at the enemy "he tried to shoot me" and then joyfully shooting back. Many wars are mostly intense boredom, punctuated by occasional bouts of terror or joy. Also there's a weird sort of release from the typical responsibilities of life -- _all_ you have to do is fight (which as fucked up as it sounds, can be more simple than worrying about the next side hustle / the wife / the kids). If you're on a rear-guard type of situation it's mostly drinking chai and smoking cigarettes.
