A question about unit on my Feldpost letter

[Rik.S]

Goodevening guys,

I was busy with my Feldpost collection and doing some research regarding some of the letters.
On one of the letters I came across a unit and I can't seem to find what unit it is.

This is what's on the enveloppe of the Feldpost letter:
2./ San. Offz. Erg. Abtlg. Leipzig Halle.

I found a website about the airfield Leipzig Halle and all the units stationed there, but nothing about the unit in my letter.
Does anyone know what unit I am looking for? I am thinking about a Sanität unit.

Your help is very much appreciated.
And sorry, but no pictures of the Feldpost letter. My phone keeps flipping them and my laptop isn't working great either.

Regards, Rik

Ok, I decided to post a picture of the enveloppe and it worked out ok.
