Here's 3 of 5 (or more) pictures of sirens I'll send. (I have all my photos stored on a My Cloud, and the website is acting up.) These ones are in Fort Hood, Texas, taken February 18, 2017.
Here's a Modulator 6024 near some of the military operations.
This siren is near a military museum. It's a Federal Signal Modulator 5020, but one of the few 5020s that has a beacon on the top. All 6024s have them.
This Modulator 5020 picture was taken at night, and I believe it's near the III Corps office. It, along with the 5020 above, has a red beacon on the top. This is also one of my personal favorites, because the lighting made it look rather cool.
I'll post the others once I get the cloud to work.
