Patrick Hennessey reads his soldier's tale for the 21st century; an account of his experiences at Sandhurst and then on deployment in the Balkans, Iraq and Afghanistan's Helmand Province. Hennessey is commissioned into the Grenadier Guards and is straining at the leash to get to the Middle East. But the British army has other plans for him - parading and primary school teaching. A Sweet Talk production for BBC Radio 4.
