[Special Ops/Covert Ops] Equipment for Mercenary Operation in 1990-1991

[Icelander]

I'm looking for suggestions, brand and model name if possible, as well as weight and stats of the kind of more expensive equipment a mercenary operation similar to Executive Outcomes would need.

That includes forward-looking infrared (FLIR) sensors and high-quality cameras and optics for reconaissance aircraft, air-to-ground and ground-to-air communications sets, radio relay for circling aircraft over the contested area, tactical radios for individual elements, night vision and the like.

If Warsaw Pact equipment is sufficiently effective and not too heavy for the intended use, this is happening right as the biggest military equipment fire sale in history was happening, so buy Eastern European if it will do the job. In 1990-1991, though, it's quite possible that Soviet tactical radios were too heavy for each man to carry one and only Western ones would be practical. Same for advanced sensors like the FLIR. Eastern Europe had lots of good lenses and optics, not sure how well integrated that was into aerial photography or live-feed video from the air.

I'm open to buying lots of cheap Soviet night vision helmets or goggles to equip drivers, pilots and even individual soldiers. No way will a reasonable budget stretch to giving everyone top-of-the-line Western gear that even Navy SEALs didn't always get, but with IR light sources, the Soviet stuff is way better than nothing.

GURPS books have generic TL8 radios and sensors, I'd like to be able to used named equipment, with real world-world and capabilities, whereever possible.
