Injured soldier (bit naughty)

A soldier got injured in a gunfight and kept screaming "medic!".

The other soldiers took him to the medical tent but he kept screaming "medic!".

The medic finally arrived and asked him what was wrong and the soldier kept saying "medic".

After a few minutes of inspecting the soldier below the waist, he realised that the soldier

Spoiler:

wasn't saying "medic!" at all.
