I mcm dah patah hati to find good squad, if they go rambo then I go rambo too. But now I'm playing the game more as sense of a "same team" than "same squad". If I see blue arrow then those blue arrow pun blue arrow la become my "squad" for that moment.

The SOFLAM is a Recon gadget in Battlefield 3. It is deployed as a stationary weapon like the M224 Mortar but is used for laser designation of targets for guided weaponry. Once set into a suitable area, the player can control it remotely (like the EOD Bot or MAV). The SOFLAM is semi-autonomous and will designate targets even when unattended.

Even if other players cannot provide guided weaponry, the player still benefits from having a remote camera with which to spot enemies and range targets. The monochrome (black & white) day-vision camera has two levels of zoom. At the bottom of the display are azimuth (heading), range, and elevation metrics.

Enemies who discover the SOFLAM can destroy it.
