When I was using the Snatch in Iraq there wasn't really a standard fit for the radios and ECM, our bowman was mounted where you have your radio but the ariel was stored in the cab. In the centre front of the frame between the front and rear we had PMR mounted so that I could get to it. To the left and right in the rear we had some ECM, I cant remember when we got the various ECM because they kept giving us more. I think we had Chubb, Baltimore another one called batter ball or somthing like that and another I can't remebr the name of. One of them would block our GPS so if we wanted to use the Garmin we either had to switch the kit off or stop, get out and walk out of the bubble. When the guys came to put the wiring in for the ECM, they just asked us where we wanted it and they fitted it there. I dont have many photos but this one has both our Snatch, all the arials were on the roof as it was the best place to create the centre of your bubble, you can see the longish arial, the short stubby yellow arial in the centre and another at the rear, the fourth arial appeared later.
We also had a spare wheel in the back with a wooden frame over the top for the top cover guys to stand on. The frame in the middle also had day sacks, camal backs and other kit on it, along with a red phos grenade so that if our vehicle was immobalised, the guys in the back could put a couple of rounds through the ECM and pop the red phos and all the kit would be destroyed.
Have you got any overall shots of your Snatch?
