The boys gettin’ in trouble again?
—A SODAR Array driver asking where she is needed
The SODAR (Sonic Detection and Ranging) Array is a Foehn support vehicle that not only detects nearby hidden enemies, but once deployed, it also enhances the firepower of all units wielding Golden Rocket launchers.
Yuri's psychic illusion technology is a major threat to the Foehn forces. Constant attacks with cloaked and subterranean units brought many casualties to their already limited armies. A dedicated unit for early detection and warning was required and the answer came with a unique SOnic Detection And Ranging system. Using a wind profiler based on Foehn's wind manipulation technology it became possible to measure and read the scattering of sound waves by atmospheric turbulence and detect any sort of suspicious activity from objects not noticeable with the human eye or standard radars. In order for the system to work, a SODAR Array must be deployed first, it does not work in its mobile form.
The SODAR Array is also capable of collecting and sending data on wind behavior to the units which rely on the so-called "Golden Rocket" weapon. This data allows them to set the launch coordinates and modify the rocket's flight path more accurately so that it hits their targets with bigger precision and deals even more damage than usual.
Acting as a support unit for the already powerful Golden Rocket-using units, the SODAR Array is an otherwise necessary vehicle for defending an area as, on top of the damage increase, it can detect stealthed and submerged units which a fair amount of Foehn offensive units are incapable of doing. While it is only able to use its signature ability while it is deployed and thus unable to move, it has a relatively large area of effect, allowing Golden Rocket units around it to give chase to enemies while still being under the Array’s influence (to an extent).
Make sure to defend it and never send it alone, though. A SODAR Array has no means of protecting itself, which, even though it can certainly be used to support an offensive, it will cater more to the defense of important structures such as production facilities, tech buildings, etc.. It is great to have while winning, as it can deny an enemy from gaining control of an area, but having it while on the losing side of a conflict is a different story, especially against Epsilon, as most SODAR Array-compatible units are not suited against large amounts of infantry and are easily swarmed in that regard. In addition, as it is a rather pricey purchase, losing one in a battle could soon lead to the loss of control in a contested zone.
