[Mobhack]

Buttoned (hard) == pinned (soft)

-Degraded chance to hit, to spot, etc
-For AFV it costs more to move (+1MP?), soft can't move till rallied up.
-No. of available shots can reduce (esp for AAMGs).
-AFV easier for infantry to close assault.
-Mine clearance rate reduced.
-Ammo resupply rate reduced.
-Negative morale effects due to the suppression for rallying
-Vehicles more likely to bog down crossing obstacles (if sticking preference is on)
-More likely to trigger mines etc

Buttoned-down AFV are closed down, i.e. hatches shut.

A little bit more than minor effect but not paralysing.
