A soldier called through to his colleagues "half a dozen times", saying shots were being fired very close to the observation post where his colleague was found fatally wounded, a coroner has heard.
Twenty two year old Lance Corporal Michael Pritchard from Eastbourne was shot by a British sniper and died in Afghanistan in 2009.
The inquest into his death heard that no one received the warnings from Rifleman Jeffrey Stanley because of poor radio contact.
Mr Stanley said the first two hours of their shift on the roof of the observation post were quiet, but at about 8.15pm he heard over the radio that the remote sangar could see people on the road, the court was told.
The inquest continues.
