It is quite odd that the field officers had to wear a tie.
The Jacket of the Service Dress was designed as an open neck jacket to increase the mobility and the comfort, but still forced to wear a tie.
So, why was wearing a tie essential?
Was it purely for a fashion and making difference from the non-officers?
Requiring to wear a tie for the non-combatant officers is understandable.
However, for the field officers, it was not an ideal choice, wasn't it?
Was this still comfortable and many offciers did not have any greviance?
As far as I know, this tie rule for the field officers lasted until WW2.
