The Demountable Rack Offload and Pickup System (DROPS) was a family of logistics vehicles formerly operated by the British Army, which consisted of two vehicle types:
- Leyland DAF medium mobility load carrier (MMLC)
- Foden improved medium mobility load carrier (IMMLC)
Both were able to transport 15-tonne flatracks or containers configured to ISO 20 feet standard and to load and offload them autonomously. Both may have been supported with side rail transfer equipment (SRTE) for loading and unloading railway wagons.
The DROP system was designed to meet the very high intensity battles in Central Europe in the last decade of the Cold War. However, it entered service after the collapse of the Warsaw Pact, but nevertheless proved a versatile vehicle system on operations completely different from those originally envisaged.
