Armband - Whats this one for?

[Reconnoiter]

Found this recently in Northern Italy, what does this Armband signify?, who would wear it? I have been told a translator or other military assistants may wear this.....
The second pic is of the marking inside, turned inside out.

Thanks for any and all information,

Rich
