There were originally two types of soldiers serving in the Bundeswehr (Federal Defence): regular units and conscripts. Consequently, there were also two types of oaths.

Translation:
The religious adjunct used with the oath was optional, the replacing of "ich gelobe" (I pledge) with "ich schwöre" (I swear) was not.
