What's Egypt got to do with South Africa, you ask? It's the badge of the Gloucester Regiment.
The Glosters were the only regiment in the British Army to wear a cap badge on both the front and the back of their caps, and it's unsurprising that it references Egypt. At the Battle of Alexandria in 1801:
The front and rear ranks of the 28th were simultaneously engaged, whereby the soldiers received the order "Front rank stay as you are, rear rank about turn" and in commemoration the regiment later adopted a second cap badge, the 'Back Number,' worn at the back of their head-dress.
The Glosters were later merged with a couple of other regiments, but their successors, the Rifles, still wear the back badge.
