Senior Aircraftman Ben Townsend is a communications technician. Along with his colleagues in 2 Squadron, 90 Signals Unit, they're in training for their tour in Afghanistan.
Ben will have extra advice at hand because his dad, Mark, is a Warrant Officer within the same Signals Unit and is already out in Afghanistan. Their paths will cross for a few days before his Dad heads home.
Ben's Squadron leaves next month and after his tour of duty, the Townsends will be reunited before Christmas.
"There is always a potential threat that something might happen, so if anything was to happen to us, then we always have to know that everyone is trained and your colleagues are at your back.
"It will be good. I am sure he will show me all the ropes when I am out there anyway but it will be nice to see him and catch up. Obviously we have only been in contact on the phone every now and then."
