The pictures sent back to Requiem make it just fine, there is nothing blocking signals in and out of this location.
From the pictures, Requiemc can easily make out several Ares Alphas and other high end Ares gear, such as a single Desert Strike, and a few Crusader's and Predators. A couple of combat shotguns and looks like they eschewed the Stoner-Ares for an RPK HMG.
Harder to make out are what's in the cases. Again, from his time with Ares he can recognize a few of the cases outright. B&E Gear, Optics, Medkits. Some of them must be for combat armor, though there are only two boxes of those.
This is literally the armory of a well-funded HTR or Assault team. Probably just one team but enough gear to account for different Ops. No different than the Arms Room of his old fire watch team.
