A fair amount of artillery was used in Gulf War II.

Its hard to hit scoot & shoot.

Collapsing the Iraqi command & control had as much to do with the lack of 'artillery duels' as anything else. Generally the Iraqi artillery was air struck, counter fired, and overun, before it recived any usefull target info. When they did get fire orders the targets were often long gone. According to the Field Artillery Journal, in Desert Storm just one of the 30+ Iraqi CBR was activated, & was destroyed "imeadiatly" due to signal intel locating it. Not much of a duel.

Not entirely true, Brit 105mm btys did have some work overcoming attempts by Iraqi 122mm and 152mm btys to destroy them, even had to move to alternative positions, first time that's happened since about 1944. It was also at night. Of course the Iraqis lacked good Tgt Acq and this gave the Brits the advantage they needed (Mamba, ASP, UAVs).

Any info on how the Iraqis located the Brits? & How they organized and executed the attacks?

Nothing reported but Iraq had acquired all sorts of stuff from all sorts of sources over the years. They also used a few 'large' rockets.
