What is the unit's 'jamming point'?

[WhiteWolf]

Hi,

I recently saw that an [object] can now modify a unit's jamming points.
I wonder what those are I couldn't find it neither in [unit_type], nor in [unit].
What is unit jamming, and what is the default value? (I couldn't find that either anywhere).

Jamming inhibits enemy units' fog/shroud vision.

Apparently it was even missing from the place where it should have been documented, which is under movetypes. I've remedied this issue, so in future hopefully people will manage to find it better.

Is there any more detailed documentation on what 'jamming' should do?

There's an elvish outrider with it in the test scenario, but it seems to have no effect. I'm moving him to 5,14, changing him to side 2, triggering the "let there be fog" tile, and then moving another unit to uncover the fog, but his presence doesn't seem to change anything.

octalot, the Outrider in the test scenario has jamming=0 in :inspect. (This is a known issue, see 0e38e4217900a07a00ca8b239ae4f06a9164b342)

It does work like this, though:
