Here is a close up of the officer and the sergeant.
The sergeant seems to hold the rank of first sergeant. Unfortunately, all NCOs of this generation playmobil western sets are first sergeants. And there is a lot of them. The former cavalry set, 3485, at least had a corporal as well. But the corporal rank is reborn with the new western sets, I believe one is included in the new fort 5245. But still, playmobil is probably the only army in the world where the ratio sergeant:privates is 1:2.
The officer has an unknown rank, as this patch with diamond is based purely on playmobil's fantasy. I allways imagined the officer in 3485 to be captain, so I guess this new officer is captain or lieutenant.
It is nice to see that the colours are correct: blue and yellow. The 3485 used blue and red - and thus confusing my union officers, since red is the colour of the artillery while cavalry use yellow.
