Great photo!! so many have no idea,how close the enemy was !!
Cameras to the left of them, cameras to the right of them.... :D
Presumably a firing party for a military funeral, seeing the cemetery behind.
Someone fairly important I suspect.
7 men there are in the pic Surpmil so I think your assumption may be the correct one.
