Thank you, Steve for sharing your thouhts and ideas - I definitely agree.
I wear the Swiss Grenzwache jacket as a casual wear, and in my opinion such definite shaped pockets are quite comfortable in use.
Besides, I have almost the same jacket with the same shaped pockets and the same cut, but black in color, with velcro-fastened hidden light-reflecting
"POLICE" (yes, in English) patch on the backside.
This fact shows that the chest-pockets of such shape are used not only in the Swiss armed forces, but at least by Boarder Guards and some police squads.
