The photo was indeed taken on Malta. That particular camouflage was peculiar to the Island, and probably not used anywhere else.

The Formation Sign is a bit problematic! The informatiom I have ( rather incomplete, I'm afraid ) gives a white eight-pointed cross on a red background for the 231st Infantry Brigade.

The Artillery on the other hand had the arms of the cross divided each into two colours; red - blue for field artillery, yellow - blue for anti-aircraft artillery, and red - white for coast artillery regiments.

The sign pictured seems to be for a field artillery regiment, but were the RA issued with carriers?

It's true that things were pretty desperate here, and they had to make do with whatever was available! For example, Matilda tanks were pressed into service on the main airfield to keep the runway open by unceremoniously dragging any crashed aircraft out of the way.

Incidentally the eight-pointed cross is the hallmark of the Order of St. John of Jerusalem, more commonly known as the Knights of Malta, and is still used today by the St. John's Ambulance Association.
