Wehrmacht (Heer) Tropical trade- or special career insignia, as intended for a 'Sanitäter' (Sanitätsunterpersonal Abzeichen). The patch is showing a neatly machine-embroidered Asklepian in golden-yellow linnen on an olive-green coloured tropical cloth, having a reinforced border. The patch is having a black linnen backing. Nice tropical version in good unissued condition!
