My method of doing this has been to give units possibly equiped with flares a vision of 5, which makes them more capable than units without, but not as capable per se as infantry with night vision systems or the like. I've done this mainly with infantry and aircraft.

When I was messing around, I actually created tracking units that were equipped with dogs, and decided that their "vision" should be increased appropriately to note the dog's ability. This might not be all that realistic depending on the ranges at which the unit can now "see" the enemy, and that this means dog's can "smell" tanks and such, but it was a compromise of sorts. In this units I created, the dogs were not added to the overall force numbers either.

The idea of the low survivability unit "flare" is tempting as well.
