If you want to know how effective pressing the "c" key might be, then review in your mind all the times the OPFOR has taken cover as a reaction to your firing. It is the same mechanism but made available as a voluntary action at a cost in MP (and therefore shots available).

Some enemy troops who take cover due to your fire will go hidden, but some will show up again. Some wont even blink out before being re-aquired. It depends on range to them, what cover they are in, and the experience of the spotter(s) and the hider too. And the spotters suppression level as well. And how many hexes the ducking unit has gone this turn (moving faster means easier to spot, as well as for non-vehicles, more vulnerable to fire). And also - has the ducking unit fired (units who have fired are easier to spot, as with movement). is there smoke around? - smoke lowers spotting chances.

So
- out in the open, poor chance
- lots of nearby experienced unsuppressed enemy spotters poor

It's unlikely to work at say 2 hexes distance to several unsuppressed spotters. But if in visibility of 3-4 (and no night fighting aids for the spotters) - may well work. A sniper in rough terrain or a building or woods and 10-12 hexes away from enemy may well get away with it.

- Spotting is more difficult, the longer the range
- Spotting stuff in terrain cover is more difficult
- Spotting things at >=50% of visibility (vision for night gear) is more difficult
- Spotting near the limit of current visibility (or N/F gear range) is also less effective. So if vision is say 40 and your target at 38, its on the edge of visibility.

The C key is therefore not a magic invisibility cloak, but an "Oh Sugar!" emergency action. In SP - popping a smoke grenade (if you have one, and the MP left to do so) is a better prospect.

There is no status message to you as the owner to let you know that your dive for cover actually worked or not. As with real life, you only would know if the enemy stops firing at you. If you take cover then try to move the unit to some covering terrain and he fires at you again - your take cover attempt may have failed, or perhaps the subsequent movement re-acquired you to him..
