[6][7] On 16 September 1941, the glen was the site of the worst single incident involving loss of life in the history of the Irish Defence Forces.

[8][9][10] This incident, known as the Glen of Imaal Disaster,[11] occurred during a training exercise involving 27 officers and men from the army's anti-aircraft battalion, artillery school, and corps of engineers.

[12] Sixteen soldiers were killed when an antitank mine unexpectedly exploded (15 dying immediately, and one later succumbing to his wounds).

[15][16] On 15 April 1979, a fatal accident occurred in the glen when a group of teenagers from Lucan who were engaging in an orienteering activity triggered an explosive which subsequently detonated, killing three and seriously injuring others.

[20] Tactical exercises also take place there, sometimes involving Mowag armoured personnel carriers and Irish Air Corps helicopters.
