Wouxun radios are an off-brand amateur radio. Yes, it will transmit on GMRS/FRS frequencies, but with how much power? There are HAM handhelds that will transmit on GMRS/FRS frequencies, but you should use an antenna that is tuned for the frequency band that you are transmitting in. Also, most radios only output a couple of hundred milliwatts in the GMRS/FRS band. To get the most out of FRS/GMRS, you need to make sure that you are using the right amount of power and a the best antenna for your application. You can get GMRS mobile rigs that will output 50watts, but that may be overkill for tactical, small-group communications.
