Yesterday I saw two Barracks spawn (different occasions, different locations), in a parking lot. Not just found them, but actually saw them appear like a heli sometimes does when you walk towards a helipad at an airport. Is this new? Or did I just never realize? Seems like a weird update, but I also have no idea why it would happen in the first place.
Ps, One was was in the western Grand Senora Desert, maybe Harmony at a store or gas station parking lot, but you never see military that far out. The other I didnt think to note at the time
They have been like this for a long time. The Barracks have spawn locations in Terminal, Grapeseed, Harmony, Paleto Bay & of course inside Fort Zancudo ... There might be more locations, but those are the ones I remember at the moment.
The one you came across in Harmony is in a parking lot east of the Lost camp (Slab City).
