The L used with Luftwaffe was different, but the army used an L look-a-like as for Munich.
But.....it however does not quite match the L for the HJ for Munich. The "open" loop at the
bottom is not present with the army; the "ball" at the top is neither present when for the army.
The basic material for the army shoulder-strap was a blueish-darkergreen, which often looks
quite dark.
The L for the army in lighter-blue with a lighter-blue piping means = Farhr-Nachschublehrschwadron
and also for Kraffahr-Nachschublehrkompanie(see "Uniformen der Deutschen Wehrmacht", 1939/1940 by
Eberhard Hettler, page 24 and color-plates as "Uniformen des Deutschen Heeres").
