Home-Army Fifth Operational Corps

The Home-Army Fifth Operational Corps — or the Fifth Operational Corps for short — was a military organisation which defended the Earth from alien threats in the late 20th century. The organisation's acronym represented the word 'Fifth' with the Roman numeral 'V', spelling HAVOC. (PROSE: The Enfolded Time)

The organisation was a successor to the previous four Operational Corps, (PROSE: Mutually Assured Domination) LONGBOW, (PROSE: Moon Blink) and ICMG (PROSE: The Dogs of War) and a precursor to UNIT. (PROSE: The Enfolded Time)

History
After ICMG was destroyed in 1966, several important people in the British government wanted to create another alien defence organisation to replace it. (PROSE: The Dogs of War)

The numerous alien attacks in early 1969 gave Major General Oliver Hamilton and Ian Gilmore the leverage needed to convince the government to create the Fifth Operational Corps. (PROSE: Mutually Assured Domination)

It was funded in large by industrialist Peyton Bryden, who wished to benefit from the advanced alien tech so that Bryden Industries could continue to compete against International Electromatics. The MOD liaison to the Corps was Peter Grant, who had a niece that was into 'spy stuff'. The HQ of the Corps was located in Dolerite Base with their troops stationed at Stirling Castle and in Imber. (PROSE: Moon Blink, The Grandfather Infestation)

The Fifth was initially commanded by Colonel Alistair Lethbridge-Stewart, who promoted to brigadier shortly before officially taking command of Dolerite Base in Edinburgh. The Head of Science & Research was Doctor Anne Travers. (PROSE: The Showstoppers)

In 1973, Lethbridge-Stewart left the Fifth Operational Corps to create UNIT. He was ordered to pretend that Corps had never existed. (PROSE: The Enfolded Time)

The Corps continued, working on some of UNIT's more secretive operations. After Lethbridge-Stewart took over UNIT UK, Walter Douglas was promoted to brigadier and resumed command. (PROSE: Ashes of the Inferno)

It continued to secretly protect the UK in 1990. (PROSE: The Enfolded Time)
