Systems are in use that counter a large proportion of these devices, but range, position in the patrol and several other factors come into play. I'm
not going to go into detail as these systems are still restricted for obvious operational reasons.
Think about it. If all frequencies were blocked, it might be a bit difficult for the patrol commander to call for help if a contact happened as his
comms kit would also be jammed. We can only study the devices we find and configure the counter measures to the most commonly used frequencies.
Many of the devices are triggered by command wire, pressure fuse, IR beam, timer, telephone/beeper etc. Systems that work on radio frequencies would
have no effect on these more traditional initiation devices.
