From my POV it depends on circumstance:
Sometimes to be strictily following CoC makes sense: I recall a Colnel once coming by for an inspection and reprimanding my guys for not having their shirts buttoned up according to rules: I had to - courteously - ask him to the side and explain I had ordered it that way (which hadn´t been the case, but it was summer and the guys sweating away had taken liberties), and additiionally I asked him to never ever jump CoC with me again, it worked, in the end he even congratulated me on my stance).
OTOH, sometimes you just have to slack it a little and have yourself shortcircuiting CoC to obtain e.g. necessary stuff w/o going through the beaurocrats mill (in the ´70s in Germany it was a nightmare just to order new batteries for the coy´s torchlights, much better to go and buy them yourself backed through a semi-black BN fonds; this has changed since, as now even coys have budgets, so I am just using this for an example).
Last, there are some (few) serious issues where you have no choice but to make a decision depenidng on your character/type: Seeing something really whacked up happening you can either close your eyes and follow the trend (it usually *is* the trend), or oppose calling in all your favours for the (from your POV) perceived better for he force, whatever harm it might (actually, will!) do to your career.
