With the introduction of the Howitzer M109, the procurement of an all-terrain ammunition transporter also became necessary. A loading crane was mounted on the loading bridge for handling the palletised ammunition (weight of the pallet approx. 380 kg). At the time of procurement, this was equipped with a pulley block, from 1980 with an electric crane. The chassis is based on the M113

The M548 (M+75696) is stationed in Altstaetten
