I looked at the Military Checkpoints around the Commonwealth and thought, "they're pretty pathetic." If this was real, would I really want to be posted there? Heck no Most just had people, and volunteers at that, standing around with nowhere to sit, no shelter, no where to sleep.  Surely the Minute-Men could do better? They're an ARMY, not a rabble like the Raiders. You would think that with a bit of scrounging, imitative and help from a few traders and their Brahmin, they could do better.

I can imagine the conversation now:
"You seriously expect me to volunteer to stand out in the rain and protect what?"
"Yes, we're the Minute-Men, it's what we do."
"In the rain, with no shelter, no where to sit, no where to sleep and no place to cook?"
"Yes."
"No way, we're an ARMY, not a rabble like the raiders. Besides, union rules say we need to have a seat, shelter from the rain, somewhere to sleep and somewhere to cook. Come on lets talk to the traders, see if we can use their brahmin to drag this old APC out of the mud, scavenge up some chair and beds and put up some shelter from the rain. And get that mechanic guy, what's his name? Sturges, out here to see if we can get the doors open on these APCs."
"Okay already, next thing you'll be wanting some light."
"Heck yes, lets see if we can find some lanterns."

So I have overhaled all of the military check points apart from one I already overhauled in North End in my earlier mod Friendlier Commonwealth - North End Apartments. They all give the Minute-Men somewhere to sit, shelter from the rain and usually somewhere to sleep. Most also add a cooking station.

I also overhauled a bar / cafe / pub on Nahant to be "The Beach House". A sort of rest and recovery site for the Minutemen with a small medical ward, a doctor, some heavy metal protection and an old familiar face.

This is a test version, I've tested most of it, and it is ready to go, but there may be floating objects.
Update 28/09/2021 - Fixed a floating lantern issue.
Update 29/09/2021 - Fixed a floating chair issue.

FAQ:

Q. Is it okay to add to the game before you meet the Minute-Men?
A. It is okay to add to a current game. It actually does not change much, just cleans up debris, moves a few existing objects and adds a few. They're standard objects. Only in one checkpoint and the Beach House does it add new NPCs. It also does not change the vulnerability of the Minute-Men, so if they have died out, it does not replace them apart from the checkpoint north west of Watts Electronics near Mass Sand and Gravel.

Q. Does it break quests?
A. Not that I am aware of. 

Q. Does it break pre-combines?
A. I'm still learning about pre-combines, so I'm not sure.

Q. Does it break combine harvesters?
A. No combine harvesters were hamrmed in the making of this mod.

Q. I found an issue / floating object / something that needs fixing.
A. Great, please take a screen shot of it and let me know.

Q. Oh hey do you know you made a spelling error on the screenshot of The Beach House?
A. Yep, I fixed it in the final mod. I'm too busy to take another screen shot.

Q. Does ....
A. Hey, I'm just an autistic person from Australia who makes mods. I don't have all the answers.

Q. I don't like your mod because .... / I want to tell you you're wrong!!! / I want to argue with you!
A. No problem, scroll on and download another mod. If you be rude, argumentative or disrespectful I'll just ban you from my mods then block you. Please just don't. I'm very autistic and can't handle conflict.

Q. Do people really ask you these questions?
A. You better believe it.
