He likes to lie back to back. it feels safe. Someone literally "has your back".
The only way I can think of expanding this is to say imagine a clock with the hands pointing to twelve o'clock all the time, I would be forward facing aware of dangers ahead of me. Knowing that I had a buddy behind me covering my '6' or my back was a comfort. That buddy would be facing away from me in the field, 'back to back' him covering my back or '6 o'clock', and me covering his in return. Hence the need to sleep back to back as we would have when deployed, all side of the clock covered, no surprises
They're different for everybody based on their own particular traumas... that's what makes it so hard to avoid them. It can be a smell, a sound, a sight, a person, sudden movement, or something random. You just don't know unless they tell you, or until they get triggered.

@Sweetpea76 could not have put it better. With Military sufferers it literally can be anything that potentially can trigger us. A smell, remember that there are strong smells in everyday life, personally, the smell of acetone or freshly cut grass send me spiraling into unfathomable danger, these are the aromas of potential chemical warfare attacks, imagine the panic when all of a sudden these smells attributed to this kind of military attack appear, In military life we are conditioned to simply "react" when faced with this kind of danger. That instant reaction in civilian life for us can be dramatic because our trauma history will send us straight back to that experience during military service.
A sound, imagine spending 6-12 months in a war zone with mortar shells exploding around you 24/7. Again for me, fireworks!. Unless I have planned to go to a display, have taken my "Buddy" to watch my '6', I am going to panic, and when I say panic, for me it literally is just that, all out got to escape panic.
It is not that we do not love our spouses/partners. For us it is about perception of impending danger, the need to protect them, if we are safe then they are safe, if we are in mortal danger (Which soldiers are every moment of the day when deployed) they our loved ones are too.
I wish I could offer more in the way of comfort
