F (Sphinx) Parachute Battery Royal Horse Artillery is a close support battery of 7th Parachute Regiment Royal Horse Artillery, part of the Royal Horse Artillery of the British Army, currently based in Merville Barracksin Colchester.

The Battery was raised in India in 1800 as an experimental Brigade of Horse Artillery. They were immediately sent to Egypt to join the force that was operating against Napoleon’s Army. The Troop sailed to the Red Sea coast where they marched across the desert. This took a heavy toll on the troops and particularly on their horses and by the time they reached the Nile the guns were being towed by camels. The Troop sailed up the Nile to Giza, home of the Sphinx, where they were encamped on the Isle of Roda. By the time they were ordered to march to Rosetta the French had given up Alexandria so the Troop never had the glory of facing Napoleon's Army in the field. On leaving Egypt the Troop returned to India where they were garrisoned at Dum Dum, Calcutta. In 1926 the honour title Sphinx was awarded to the Battery for services in the 1801 campaign against the French in Egypt.
