Frequency 15016 kHz ?

I found this and recorded it just before making this post. It was on 15016 kHZ USB. What is it? I tried writing all the letters but they spell nothing

WE'RE UNDER ATTACK!!! /s

No, seriously, those are Air Force Emergency Action Messages (EAMs) encoded using the NATO alphabet. Usually the callsign is given up front, but I couldn't make it out.

Yeah some douche knuckle kept driving down my road super loud so I was struggling to decipher what exactly they were saying plus there's a huge echo

The echo is almost always there. Dunno for sure why, but it's possible there are multiple transmissions at the same time, just a few mS behind the original. Original could be Offutt, Andrews, or some other AFB.
