Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- Roland SAMs are manoeuvrable, and do not decelerate like other SAMS
- Can take down aircraft and choppers up to 8.5 km (5.2 mi) with the Roland 3
Cons:
- Roland missiles are slow
- No anti-aircraft cannons as backup once all missiles are expended or for use against close-range/ground targets
History
Selected in 1975 as the forward air defense system for U.S. Army divisions, the first missiles were delivered in 1977 with the first firing from the XM975 launcher vehicle (a modified M109 howitzer chassis) taking place in September 1978. (Prior to late 1977 it was planned to use a version of the M520 Goer as the launcher vehicle.) American Roland was essentially Roland 2 with a longer-ranged American-made search radar. The palletized fire unit could be installed and rapidly removed from the XM975 chassis, installed on a truck or used as a static emplacement. Problems with technology transfer and rising costs (ostensibly at least, institutional resistance within the U.S. Army/DOD and Congress to using a 'foreign' weapons system may have actually played more of a role) killed the program and only 27 fire units and 600 missiles were built for one battalion in the Army National Guard, mounted on M812 flatbed trucks. With the failure of the M247 Sergeant York the U.S. Army leased 5 German Roland systems for evaluation as a possible replacement.
