Between 1966 and 1973, RMAF received 18 of these rugged short-haul transport planes. Made by DeHavilland Canada, the DHC-4A, was also better known as Caribou (which is a very large species of reindeer).
I remember seeing these rather ungainly-looking aircraft — note the huge tail fin — flying at low speed around the airbase in Butterworth, with the typical low-frequency droning from its two piston engines. They could carry up to 36 troops, or 3640kg of cargo, and land on grass strips.
These have been retired since September 2000, and replaced by Indonesian-made aircraft. But there are specimens on static display, one at the RMAF Museum in Sungei Besi (KL), and another one at the Army Museum in Port Dickson. I have visited both places in recent times.
