- As soon as An AI unit gets hit with a bullet his knowsAbout level for the unit that shot him will instantly jump to 1.5, even if the shooter is 1000m away.
Vice versa is also true. If An AI soldier's knowsAbout level for an enemy is 0.7 and the soldier fires and hits the enemy, his knowsAbout level about the enemy will instantly jump to 1.5. - Some editors have found, whilst using this command over the years, that the following characteristics have cropped up:
- AI enemies have a very limited amount of peripheral vision, it is not nearly as good as a human player's. A target must be in front of the unit for him to be noticed, so if you sprint right behind an enemy, this value doesn't increase.
- Depending on the unit's skill level, it can take a little time for the unit to notice a target. So if you run right past a unit, this value might not increase.
- Bushes between the unit and the target seem to have little effect on this value, and trees definitely have no effect. You may be in a forest and can't see the unit, but he can see you.
- As soon as An AI unit gets hit with a bullet his knowsAbout level for the unit that shot him will instantly jump to 1.5, even if the shooter is 1000m away.

- the magic knowsAbout number is 0.105 It's not that simple. Maybe true for infantry but not all vehicles:
Reveal command sets knowsAbout to 1, but planes still won't fire at soldiers on the ground. There's only one known way to pass through this - designate target with another fake infantry unit near the target. As soon as this fake unit see the target knowsAbout lifts up to 2.5-4 and even single enemy soldiers are attacked from the air (of course if plane has suitable munition :)) - Posted on June 13, 2012

- According to Suma:
All friendly units within a view distance to each unit [are revealed (to the player? or each friendly?)] on the mission start. The code is half broken, as it does not make the units known, it only sets the "accuracy" value for them.
Note: This is not affecting enemy units at all. - Posted on March 27, 2013

- 1.62 infantry tests:
It is still true that the command returns values between 0 (lowest) and 4 (most). Freshly Spotted units will have at least 1.5, slowly decreasing when the target disappeared.
The following table shows my test results on a clear day in Takistan using the Vector. Please note that the returned values vary considerably depending on weather and time. Moonlight however seems to not have any considerable effect.
