I've seen some Recce Wiesels with signs suggesting DSO. Just the division, with no unit markings on the vehicle. Production version, not the early prototypes.I can remember having seen somke photos of Recce Wiesels in use with some Jäger unit but I can't remember which unit.
Presumably LL-Aufklärer, since those (LLAufklKp 310) already tested the prototypes, replacing their Wiesel TOW (used for the WBG) with them.
