Vhf low band has very long range so you can hit ht to ht from 5 to 10 miles and mobiles at closer to 20. When talking to aircraft its even farther than that

Satellites, of course.
Don't believe that a terrorist leader can listen to the White House.
Soldier/soldiers use the proper radio set up to access the satellite.

The terrorists use P25 trunking, phase 2 in the clear. In order for them to hear the White House, they use VHF low band, usually in the 39-40 MHz range so that they can catch skip openings to locations overseas. The Unidens decode these talkgroups very well, but Whistlers have to be tweaked if you want to hear all the West Wing main dispatch and tactical groups. During times when propagation isn't the best, the terrorists move to 3.943, 7.200 and occasionally 14.313 MHz. Oh wait, this isn't April 1? Let's see what Art Bell advises.

One common form of military comms for long distance is UHF Satcom where the transmit around 290 to 320MHz to the satellite and receive around 245 to 270MHz. There are lots of radios that do this from early models like Motorola URC-101, URC-110, LST-5 and Cincinnati Electronics PSC-3 and HST-4 to more modern radios like Harris PRC-117, PRC-152, Thales PRC-148, Raytheon PSC-5 and so on.

You can successfully uplink to the satellites with as little as 5w into a small fold out cross dipole over ground plane and get to anywhere on your side of the earth. These satellites are in geosynchronous orbit bout 35,700km high.

There are some Russian UHF 300 MHz mobile phone links that leak into the uplinks of the UHF satcoms. I imagine the DOD hasnt complained because NSA got to listen for free on the 266 MHz downlinks over the years.
