In some respects I'm very old school. I think one of the greatest mistakes the modern U.S. Army made was disestablishing the regimental system.
Our regiments are (today) just name and tradition holding formations, there don't actually do anything administratively or tactically.
The battalions are the administrative and tactical formations.
About 3 years ago the Danish Royal lifeguard
arguably committed active mutiny. (and all the rest passive mutiny)
Pretty much every company, battalion and regiment in the military got a Facebook page they use to tell families and the public about that is happening with the unit. This development came from the units them self and was not from the top and there where no standard for things like the page profile picture.
So someone in the ministry of defense decided that all facebook pages should have the very boring "public management" logo that some designer have made so there was no question of a page was official or not.
This change was to be done by 1st january 2018 and this was ordered.
Also at the same time it there had been some serious political talk about disbanding the regiments...
By mid january that year only the 4 branches of the military had done this, but none of the officers schools, regiments or lower formations. And the story was getting attention on the official Facebook page of the military... and the reactions where very very negative. And the one military focused media here was starting to cover the story.
And a lot of current and former soldiers, including some high-ranking one where replacing their own profile pictures with units markings.
And a retired admiral publicly asked people to do this and remove their "like" from the page for the defense department.
So a clearly order was issued that this change should be done for all organizations.
Two days later the facebook page of the royal lifeguard got a now profile picture.
Not the boring logo for the military... but a photo of the Beret insignia of the regiment.
The post had this text:
"Fordi regimenter og deres enhedsmærker er lig med tilhørsforhold, sammenhold, fælles oplevelser, kammeratskab og korpsånd"
(Because regiments and their unit insignia equals belonging, community, common experience, comradeship and esprit de corp.)
So not only was a (stupid but) legal order being ignored by most of the military... the Royal Lifeguards just very
publicly flat out refused to carry it out...
The next day the chief of defense had to back down and accept defeat...
(or alternatively he would have had to actually charge pretty much every regimental, battalion and company commander in the military with disobeying orders...)
Traditions do effect combat effectives... but that is something that is hard to understand for a civilian paper-pusher and even harder to put into a excel spreadsheet... and use it as a factor when looking at the economy of a military.
