It had a chapter/section on Garrison Leaders which struck a cord with me to the extent I wrote a piece on it for the Rhodesian Army Quarterly Magazine.

Google Books provides the following snippets:

"Good garrison leaders, for example, were found to be aggressive, as were combat leaders, but were also found to do better if they were sticklers for the rule book, athletic, possessed a passion for detail, had a good physical bearing and personal tact. None of these were found to be relevant for an officer to be effective as a leader in wartime."
Quick in and out six month tours also suit these garrison types as they can get the campaign medals with the least effort (and probably in a post with the least risk).
