From the comments:
The army and the Marines have an ongoing dispute (the army is much bigger and probably isn’t much aware of it) with respect to which is better, the army’s Blue Force Tracker or the Marines’ C2PC via EPLRS. Like any software made by the Marines, C2PC is clunky, slow, and hard to work with. But it is encrypted. The army system is easy to use, fast, handy and it works right all the time. The problem is that BFT isn’t encrypted (this was several years ago, I had heard they were changing that, let’s hope so). So, if you knew how to get at the BFT data you could see where everyone is all the time.
This is in the comments to a post about the fact that drone video streams are not encrypted. Amateur hour. And in the comments they say that the blue force tracker isn’t encrypted either? WTF?! We’re broadcasting our troop locations out there for everyone to see… wow, these people deserve to be shot. Instead, it’s our Marines and soldiers who will be shot, while the idiots who put this system in place will get promoted and lucrative private sector jobs.
