Thanks to whomever allowed me to post links!!
A simulator like Command really allows you to see the bigger picture and see how some of these units work with other offboard sensors and systems, a lot of the time in other simulators large portions of the rest of the battlefield aren't adressed, so you don't get a complete picture of how things might happen in a real world scenario.
Take the info below for example:
http://www.fas.org/spp/military/program/sigint/androart.htm
Large-scale combat US operations were supported by the satellite system for the first time during the war with Iraq in 1990-1991. Despite the very long periods of operation of the satellites (some of the Chalet satellites had at that time been in orbit 11 or 12 years), at the time of the conflict they were put on a round-the clock schedule. The task of intercepting Iraqi radio conversations from space was made easier by the fact that they were for the most part using Soviet communications equipment of the sort the satellites had been designed against.
As a result of retargeting space-based SIGINT apparatus on the Iraqi radio nets, the volume of intercepted information significantly surpassed NSA's processing capability. Consequently the American command was forced to take urgent measures to increase the number of Arabic translators.
Along with carrying out the mission of strategic reconnaissance against Iraqi military C2 radio nets, the United States made special efforts to intercept information of tactical significance (e.g., the fact of airplanes taking off or the movement of tanks as revealed by the radio conversations of the crews) and to deliver it rapidly to users in the theater.
The missions carried out by space-based SIGINT systems expand as satellite hardware is modernized consist of the following:
- intercept and decryption of governmental, military and diplomatic communications transmitted by radio
intercept of ESM (RES) signals which characterize the operating modes of the higher command organizations, installations of air defense, ABM and missile forces, and also the combat readiness of foreign armed forces
reception of telemetry signals during ballistic missile tests
relay of radio messages from CIA agents in foreign countries.
According to data in the foreign press, the band of radio frequencies which can be intercepted by SIGINT satellites stretches from 100 MHz to 25 GHz. This, however, is difficult to realize in practice as there would have to be a collection of large-scale antennas of differing forms on a satellite. The satellites probably employ the widely used modular principle for combining equipment to carry out specific reconnaissance missions. This is indicated by the simultaneous deployment on orbit of several different groupings of SIGINT satellites (Rhyolite and Chalet, Vortex and Aquacade), which conduct reconnaissance in different parts of the radio spectrum.
So going by the above, you can see how satellites can give considerable amounts of intel on the placement and type of SAM systems, radio communications by opfor ground forces and their plans, etc, using public info that's over 20 years old.
And if you don't want to destroy the enemies satellite system, there's tools for that too.

WASHINGTON (Reuters) - The U.S. Air Force quietly has put into service a new weapon designed to jam enemy satellite communications, a significant step toward U.S. control of space.
The so-called Counter Communications System was declared operational late last month at Peterson Air Force Base in Colorado Springs, the Air Force Space Command said Friday in e-mailed replies to questions from Reuters.
The ground-based jammer uses electromagnetic radio frequency energy to knock out transmissions on a temporary and reversible basis, without frying components, the command said. "A reversible effect ensures that during the time of need, the adversary's space-based capability to threaten our forces is diminished," said Capt. Angie Blair, a spokeswoman. "Following the time of need, the space-based capabilities used by the adversary can return to its original state."
The device appears to have been put into service considerably earlier than had been projected by the Air Force as recently as February. At that time, a long-range planning document, dubbed the Transformation Flight Plan, said such a system would let the United States by 2010 "deny and disrupt an adversary's space-based communications and early warning" of attack. U.S. military control of space is one of four missions spelled out under a national space policy adopted by former president Bill Clinton in 1996.
The goal is to make sure U.S. forces have unhindered access to space and space-based services and to deny an enemy any similar benefits. The U.S. military has experimented with a range of "antisatellite" (ASAT) weapons, including lasers, to knock out enemy craft by destroying them or damaging their sensors.

In the above link this public 2003 report shows budget info for projects, of interest I found was (Page C-18) "Hypervelocity Rod Bundles"
Page C-12 "Space Based Radio Frequency Energy Weapon"? Page D-10 "satellites containing high-power radio frequency transmitters that possess the capability to disrupt/destory/disable a wide variety of electronics and national-level command and control systems. It would typically be used as a non-kinetic anti-satellite weapon."
Putting it all together and you have a pretty potent force that literally has the high ground.
Then there's the rather shady Space Based Laser program, there's literally not much public info after 1999.

Going by the info, there was apparently one full size one made.
Parent company info here:

They apparetnly worked on a laser blinding Bradley that had two units fielded during the 1991 Gulf war.
among other Directed Energy Weapons.
