How is The Fort Hood barracks and living conditions for a single soldier, on a scale of one to ten?

PV2 Hale they are in the process of remodeling the last of the older barracks here at Fort Hood. While you have a chance of landing in one of the older barracks, you will most likely be placed in a newer or remodeled barracks. I can't rate on a scale of 1 to 10 because I don't have any other service experience to compare it to. Regardless of where you live the army will provide you with the space and furniture you are authorized in accordance with applicable regulations and the common table of allowances.

I was only at Ft. Hood once for a field exercise. The field was very nice. :-)

Do push ups. When I was in the Army only Air Force POGs lived in the barracks. We would set up a bed of leaves in a bears den and burn bear scat for warmth. If it rained, we would look up with the stare of death and tell God Almighty to shift right. We didn't need boots, we simplied polished our feet with soot from our bear scat fires. We didn't need prurified water, we would lock up any harmful bacteria to attention then force march it out of our drinking water. We didn't need a compass or map for land nav, we just looked at the horizon and intimated our objective to come to us. We never got cold and needed snivel gear, the heat from the fear we put into our enemies kept us warm. My God what has the Army become??

It depends really, when I first got to Hood I was attached to rear-D and the barracks were like a 5 star hotel almost brand new, but this lasted about 2-3 months,,,,,,,,,once the unit returned we were placed a couple miles down battalion ave in some real shitholes.....but just like the army, it's what you make it.

Hooah Sergeant....

"Barracks, what are those?"

Well said SGT Ben Keen. That's much like what I would tell new Airmen about their new assignment. If you think it's going to suck, that will be a self-fulfilling prophecy and it will suck. But if you think it will be good, you will find things to do and it will be a good assignment.
To the OP, I'd say do not get wrapped around the axle about housing. Lots of things within driving distance of Fort Hood.

One thing the Corps taught me, every place you go, your attitude determines your enjoyment of the place. Much like Maj John D Benedict said, if you think you're gonna hate it, you will because you won't seek ways to make it enjoyable. The opposite is also true. Your attitude determines your altitude as the old quote says. Semper Fi.
