French troops throw smoke bombs for camouflage.
French troops throw smoke bombs.
Location of events unknown / unclear.
4 French Army soldiers trot up a road between fences with criss-crossed barbed wire.
They and others start throwing something - grenades or more likely smoke bombs to camouflage themselves; the whole background is hidden by thick white haze of smoke.
Wide shots of the soldiers running farther away; jumping down (into trench?) then starting to return.
