how really morale works ?

[liga]

the manual in several time todl about morale checks ... but I wasn't able to find anywhere (not also here in teh forum) an explanation of how really it works. I think there is a unit morale vlaue and a squad morale values.

The unit value is used for personal check, the squad value to determinates routes.

But

1) how is the unit check ? is a 2d6 + morale values of the unit against what ?

2) When a unit make a check and how the result of this check has influence on squad morale ?

3) How is determinated the squad morale value and when the squad route ?

4) Has the leader morale and/or leadership some influence on the squad morale ?

thank you and good play to alla
