FO/FAC team

Forward Observer and Forward Air Control Teams might be "pure" dismounted infantry or the dismount section of a FO/TACP vehicle. However, once dismounted, the team's views and designation process (as well as the call to support) are identical to that of vehicle mounted systems. Although technically different elements, with differing equipment and roles, in Steel Beasts Professional both FO and FAC teams are functionally identical.

In the observer position F8, the squad leader's position is visualized by a little 3d model of binoculars.
F7 switches to a first-person view of the squad leader.
Pressing N provides a magnified third-person view (and only if the Realism setting is Low or Medium (Rev. 3.002)).
Pressing N will toggle the binocular view which can not be used to generate target coordinates.
Pressing F2 activates the forward observer's sight which is identical in layout and function to the Ground/Vehicular Laser Locator Designator (G/VLLD) found on the M981 Fire Support Team Vehicle (FIST-V).
This sight features a thermal view as well, which can be toggled by Num +. Additionally, NVG (Night Vision Goggle) or thermal (JIM-LR) views for the squad leader/members (Num +) are available under appropriate lighting conditions if the team is so equipped (rev. 2.640).

Note that a dismounted FO/FAC team does not have access to the mounting vehicle's coordinates when calling for fire - they have to use their own sight.

Note that in the current version of Steel Beasts Professional PE it is possible to use the FO/FAC commander's binoculars and the forward observer's sight from within buildings (rev. 2.640).
