Mesh Separation?

[SummGai]

is it possible to separate parts of a mesh into different parts, ie: i want the shoulder guards of one armour but it's slapped together with the main chest armour so can i split it and if so how and what do i need to separate?

Assuming you're in 3ds Max:

 

Select by object or faces you want detached -> click detach -> you now have seperated whatever you wanted to seperate.

 

Assuming you're in every other 3D application:

 

Same steps, might be named differently though.
