[Carl Vehse]

"Engineering casualty is an old term and quite common."

Like "collateral damage"?

[LonePalm]

No. It is to separate it from personnel, weapons, deck, electronics, etc.

Engineering casualties relate to propulsion, electrical generation, fire pumps, and other related equipment.

You should not read anything sinister or misleading into the term. So far as I know it was in use before WWII.
