South Boston military checkpoint

The South Boston military checkpoint is a location appearing in Fallout 4. The player character is called to it by an old world military beacon Emergency Frequency RJ1138, calling all South Boston Army soldiers to its co-ordinates.

It is located directly west of the Castle and past the bridge just outside of the South Boston area. It consists of 2 structures, the main building and a trailer along with various car wrecks. Notably, the main building has an Expert safe with plenty of ammo, various loot chests and behind the structure is a full suit of T-60 power armor behind a Master terminal.

Notable enemies are two gunner commanders and a single gunner, all using plasma pistols and carrying plenty of ammo.

Layout
One main building surrounding by slight rocky hills, surrounded by broken metal fences with plenty of cars which pose a threat during the ensuing fire-fight. Inside is a single room containing chests, first-aid kit and various loot along with a safe on the back wall behind a large pillar.

A Fat Man can be found inside the trailer.

X-01 power armor can be found behind the building locked behind a Expert terminal. This seems to be leveled, as below level 28, one can find T-45, T-51 or T-60 armor.

Located on the roof is a corpse with a hardened sniper rifle. It can be accessed by jumping on the cage from the bench, or with power armor equipped with jet boost.

Appearances
The South Boston military checkpoint only appears in Fallout 4.
