All of my friends and I have switched to 2M HAM HTs for tactical coms... blows GMRS/FRS out of the water in most any parameter. With the rubber ducks on 1 watt one mile comms through eastern woodland is not an issue (assuming there is no high dirt in between) I have reached repeaters out to five miles (through woods) with the duck antenna on mine and 20 miles with a yagi/directional antenna. Cities mess with it a bit more, but you could go down to a narrower band too. We have more practice to get in but it has been a great, and fairly inexpensive move.
I don't know about those specific models, I would hunt for reviews, but I know its a good brand.
