Unit/tactical marking

[photo-war]

Hello! I would appreciate any background information regarding this marking. Any thoughts for what this (unit?) marking stands for?

[byterock]

It is an Artillery tactical symbol.

Not familiar with this exact meaning but I think it must be a headquarters vehicle for the 1st battery of some arty regiment??

How about a mountain gun company or mountain artillery unit.
The men in the photo are Gebirgsjager.

[Admiraal]

I would say first battery, artillery.

[Simon O.]

A vehicle belonging to the I abteilung of a gebirgsartillerie regiment.

If you know anything more about the photo or if there are others you should be able to narrow it down as to which regiment.
