Ian ("Chunky") Gilmore was an RAF officer. During World War II, he flew missions over enemy territory, witnessing the firebombing of Dresden in one instance; he tried to push that to the back of his mind. In 1961, he was chosen to head up the new Intrusion Countermeasures Group (ICMG). (MA: Who Killed Kennedy)

In 1963, he was Group Captain for a company of infantrymen drafted from the RAF Regiment. As Group Captain and ICMG leader, he was the nominal commander during the Shoreditch Incident of the same year, but was out of his depth and ended up subordinate to the Seventh Doctor. (DW: Remembrance of the Daleks)

Following the Shoreditch Incident and resulting disbanding of the ICMG, Gilmore campaigned for a replacement group with greater facilities and a permanent rapid-reaction capability. He proved unsuccessful. (MA: Who Killed Kennedy)

Following the London Incident, he met with Colonel Lethbridge-Stewart and informed him of the Shoreditch Incident. (MA: Downtime) He later suggested the Colonel as head of the British branch of UNIT. (MA: The Scales of Injustice)
