Data Terminals. The large typewriter looking one is a DT-200 and the smaller brown one is a DT-170. I haven't worked with the DT-200, which would be used in an office type environment. The smaller DT-170 is used in the field. You type in the information to be sent and then burst transmit the report via radio. We used it in conjunction with the C-21 radio, which has a frequency hopping function. All units operating on your radio net had a pre-determined 6 digit code for each day that would enable the radios on that net to en-code and de-code transmissions so that their frequency hopping was synchronised. In this way you could transmit 2 foolscap pages of data in 3 seconds, changing frequency 6 times during the transmission. Anyone else listening in on the transmission would just intercept a fax type tone signal and at best would get a half-seconds worth as they wouldn't be able to hop frequencies with you. Burst transmitting like this also lessens your transmission time and gives an enemy less time to use direction-finding equipment to triangulate your position. The DT-170 pictured is connected to its printer unit. - [Thanks to Steve. (You know who you are!)]

Police BO-105 Helicopter

Jakkals air-droppable vehicle. It is used to meet mobility requirements during airborne operations. There are several roles that this vehicle is used in. It acts as a command vehicle with radio trailer, an anti-tank system with a 106mm recoilless rifle, a heavy machine gun platform mounting twin .50 cal machine guns, or for towing mortars or anti-aircraft guns.
