Is this some kind of proto-Kampfschwimmer?

[Von Thronstahl]

I need help with these 2 pics. They are dated 1916 so I decided to put them here in the Imperial militaria table. I wonder if they show some kind of ww1 proto-Kampfschwimmer.





And here are back sides with some text which I can´t decipher:

[RAO]

"Rummelsburger See"

Rummelsburg is a town in the near from Berlin!

and

"Car Park (place to park)
for snow bridge construction"

may be the writer is wrong and to mean "fast bridge construction", I think so. In german it is:

Schnell = fast
Schnee = snow

I hope you can understand what I to mean.

All the best,

Mike

It could be a swimm suit used by pioneers to cross a river to help with bridge construction.

Just a guess.

[Von Thronstahl]

Thank you for your help.

Maybe it really is some kind of suit used for work in river in harsh winter conditions.

Pioneers called it the virgin's dress.
