Operation Banner is the Army's longest continuous campaign in its history with more than 300,000 personnel serving and 763 directly killed by paramilitaries.
The intensity and pace of operations is an order of magnitude lower. The monthly KIA average in Northern Ireland was 1.67, for instance. The total number of people, civilians and combatants included, killed in NI over a thirty-year period is under 4,000 --- that would be a decent two-month stretch in Iraq.
