Casualty Estimates for Conflict with Iran – Killed and Wounded

Sometimes in the discussion of casualties, people confuse the word “casualties” with killed. Casualties are all those people who are killed, wounded, missing or captured. It also sometimes includes Disease and Non-Battle Injuries (DNBI), or those injured or killed in accidents. For example, in the Mayaguez operation in 1975 there were 18 Marines killed in action, 3 Marines missing in action (and captured?) and 23 people killed in a helicopter accident before the invasion of Tang Island.

If you are doing a casualty estimate, it can either be based upon total killed (in combat or from all causes) and may include wounded. Depending on the combat situation and wounding agent, the number wounded is often between 3 to 10 per person killed (see War by Numbers, Chapter 15: Casualties). In the case of air to ground strikes, we would expect the wounded-to-killed ratio to be on the higher side. If there is good medical care, this also affects the wounded-to-killed ratio.

So, with President Trump mentioning an estimate of 150 killed, are we then looking at 600 to 1650 casualties (killed and wounded)? Were they really looking at over 1,000 casualties from the air strikes in three locales? That is hardly a “surgical air strike” to borrow a phrase from the Cuban Missile Crisis. It is possible that someone garbled the phrase killed and casualties. This has happened multiple times before.
