На геймфак нашел,про ФМ 2 но написано что все то же что и в первой части --
GEO EFFECT [GEOF]
------------------------------------------------------------------------------
Unlike most strategy RPGs, Front Mission 2 makes use of the terrain as a
vital part of any mission. Each square on a map has a geographical rating
known as Geo. Basically, Geo affects the unit's evasion when under attack.
The Geo rating of the square that the attacked unit occupies is factored into
its evasion. In other words, it lowers the weapon accuracy of the attacking
unit's weapons. The amount deducted has not changed from Front Mission 1st;
if a unit is attacked on a square with a Geo rating of 20%, then the drop in
weapon accuracy is 20%.
There are some changes to Geo Effect in Front Mission 2, however. The most
noticeable change is that the obstacles on a map affect the Geo rating of
its nearby squares. For example, urban terrain such as paved roads offer a
Geo rating of 5%. However, if there is a car on the road or if there is a
building nearby, then the Geo rating of squares near them will be different.
Basically, the more obstacles that lie near a square, the higher the Geo
rating. Fight weapons are no longer affected by Geo Effect as it would be in
Front Mission 1st though.
Also, since the new Mobile parameter serves as a unit's evasion parameter,
a unit only receives the full Geo Effect bonus during counterattacks or if
it chooses to evade the attack. That is, the Geo rating of the unit's square
will be directly added to its Mobile value. So if a unit has a Mobile rating
of 20 and is standing on a square with a Geo rating of 20%, then its evasion
when it takes evasive action is 40%. Geo Effect does enhance the evasion of
attacking units, but the bonus is not direct and only a small portion of the
Geo rating is taken into account.
In other words, always stay on squares with a lot of obstacles nearby to give
your units the best possible evasion rates. Your units will avoid taking a
lot of hits and minimize damage as a result of this. However, when you attack
the enemy, make sure you lure them out to open ground where your own attacks
are more likely to hit them.
