Two arm-beams for launching carry each one a missile in its launching tube, and two ammunition stores for munitions each contain one 4 shot mechanism forautomatic unloading of the arm-beam. The crew of the vehicle consists of three man.
Three operating modes are available in the ROLAND 2: the optical mode; the mode radar; and the optical mode recopy-radar or radar-recopy-optics. Whatever operating mode is chosen, the target is detected by the radar, search in site and the continuation of the target after acquisition is carried out manually in radar mode. In the third mode, one of the means of continuation is controlled to the different one, which facilitates their communication. After the firing, the optics or the radar remain pointed at the target, the computer generates the commands for guidance by using two different groups of measurements: starting from the measurement angular velocities of pointing and programmed values of the distance precise alignment is obtained while adding to the result preceding the commands necessary to the correction by the real variations of the missile compared to the axis of aiming measured by the infra-red goniometer (optical mode), or compared to the direction of the target the commands are transmitted to the missile by the transmitter of remote control.
The missile is ready with the shooting inside its container (tactical packing), itself placed under the arms launchers of the tank. The vehicle has two missiles ready for firing and eight in the trunks.The American ROLAND program was canceled in September 1981. Previously, low-rate production (LRP) had been approved in FY 79 and FY 80. The initial LRP contracts were let in October 1979, with planned procurement based upon the eventual production of fire units and missiles to support a four-battalion force structure concept. Subsequent budget decisions by President Carter reduced quantities at first to a two-battalion force, then to one battalion. The DOD budget approved by President Reagan in March 1981 originally redirected the program back to four battalions, until it was decided to terminate this effort.
