[SGII] Mortars questions

Hi,

How do you guys handle mortar's in a game of SGII? I am thinking that
two 
mortars per company (at battalion level) is probably a reasonable level
of 
support, but with an observer at company level, with specialist
equipment 
this produces a dead on hit except when a 1 is rolled for observation
and or 
accuracy, this is usally pretty devastating to infantry.

How many actions of fire would you allow per game? How long between 
re-loading/re-suply?

Are there any counter battery rules (is this realistic for mortars?)

Loads of questions, please help

Richard
