Some sort of "Manual" For the games more in depth mechanics?

I want 2 know more in depth about , Armor, Stamina, Suppression, Bullet Cal and penetration etc...
Is there a place 2 read about those things?

Second this, bullet penetration and damage mechanics are still a mistery for me.

Bullet penetration is based on the round. Not sure beyond that but there is definitely bullet penetration through things you wouldn't think is possible.

@kraeyq Well yeah, that's exactly what I would like a guide about; what calibers can penetrate what materials and barriers.
