I'll guess from the context that MI stands for Military Intelligence. (an oxymoron, but that's an old joke.)

Here is a partial list of other possible options from Medical Dictionary: MI Abbreviation for myocardial infarction; mitral insufficiency. MI abbr. 1. Michigan 2. military intelligence 3. myocardial infarction Abbreviation for Myocardial infarction, see there, also Medical inspection Mental illness Metabolic index Migration inhibition Mitotic index Mitral insufficiency Motility index—GI

Thanks.

Looks like it stands for military intelligence.

Why write a great comment but abbreviate to the point that a reader doesn’t understand it?

Mission Impossible? MI - 5 or - 6 (Bond, James Bond)?
