At acumen7’s virtual Christmas cocktail party, the guest speaker Colonel Gary Sullivan OBE gave an informative overview of The Staff Corps, which is a part of the Royal Engineers in the British Army Reserve. The Staff Corps is intended to provide advisers on engineering and logistics to the British Army at a senior level. Following its work creating the NHS Nightingale Hospitals the Corps was described as ‘probably the greatest military unit you’ve never heard of. Established in 1865, the current officers are mainly chief executives, directors and senior managers of 60 different engineering, transport and logistics organisations, which together employ 100,000 people. As well as explaining the background to The Staff Corps, Gary also gave overview of operations it has been involved with including the NHS Nightingale Hospitals, the forthcoming mass vaccination programme, the Beirut Port recovery and Whaley Bridge.
