A Royal Marine who threw himself onto an exploding grenade to save the lives of his patrol has been put forward for the UK's highest military honour.Lance Corporal Matt Croucher, 24, a reservist from Birmingham, survived because his rucksack and body armour took the force of the blast.He was part of a reconnaissance troop in Helmand Province, Afghanistan, in February, when the incident happened.The Ministry of Defence said he could be considered for the Victoria Cross.L/Cpl Croucher, a member of 40 Commando, had been searching a compound south of Sangin which was suspected as being used for making bombs to attack British and Afghan troops.When a Taleban booby-trap grenade was tripped, L/Cpl Croucher jumped on to the device to absorb the force of the explosion with his backpack as his comrades dived for cover.The blast blew his rucksack more than 30ft away but he remarkably suffered only severe shock and a bloodied nose in the incident.
