The Honourable Artillery Company is the oldest Regiment in the British Army and they were holding an open evening that day as a recruitment event but also to raise money for charity. This has now become an annual event and it is only on for 3 hours but entry is free and they certainly pack a lot into that short space of time.

We arrived shortly after the doors had opened and there was already long queues at the food tents where free (donations gratefully accepted) burgers, Chinese noodles and mini pizzas were being served up, next to these was the beer tent.
We did a circuit of the static displays, field hospital, survival equipment, ordnance vintage and modern but best of all was the Chinook, surreally parked before the high rise offices of the City.

The programme opened with a display of exercises by the Kings Troop Royal Horse Artillery towing a 13lb gun, personally I never tire of watching them wheel those guns around.
Next up was a display by the Company of Pikemen and Musketeers

The HAC is a Territorial (Reserve) Regiment of the the British Army which specialises in surveillance and target acquisition for the artillery, members of the Regiment have been mobilised for service in Iraq and Afghanistan.
Next followed two displays by No. 2 squadron, the first was set during the Boer War and involved calling up the guns to support infantry ambushed by a Boer Kommando. The second was a similar scenario set in modern day Afghanistan. Both displays involved lots of explosions and much smoke, I love this kind of thing.
