Belts became part of formal military clothing (compare baldric sword belts, and cummerbund). So several other modern soldiers wear seat belts to be worn by the police in military uniforms. These include the Norwegian armies (red-blooded belts), Sweden (yellow and blue), Greece (blue and white), the Netherlands (orange), Portugal (blood red), and Spain (red and gold generals, regular blue officers, and red officers). The Spanish Regulares (foot soldiers from colonial policies previously recruited in Spanish Morocco) retain their historic belts at the waist of all levels with different colors depending on the unit.
The French Foreign Legion sachets are blue.
The modern British army retains a red belt to be worn by a certain sergeant and in addition operates on foot troops, over the right shoulder to the left waist. The same red silk net belt is worn around the waist by the officers of the Foot Guards wearing a full red robe and the officers of the soldiers marching on the blue "Number 1" uniform. The same practice is followed by other Commonwealth forces.
