South Boston military checkpoint

The South Boston military checkpoint is a location appearing in Fallout 4. The check point broadcast an old world military beacon Emergency Frequency RJ1138, calling all South Boston Army soldiers to its coordinates.

It is located directly west of the Castle and past the bridge just outside of the South Boston area. It consists of two structures, the main building and a trailer along with various car wrecks. Notably, the main building has a Master safe with plenty of ammo, various loot chests and behind the structure is a full suit of leveled power armor behind an Expert terminal.

As of 2287, the checkpoint has fallen under Gunner control, with an unnamed Gunner commander in charge of it.
