We play that all cities count as a liberation point regardless of where they are, and allow terrorist units to be broken up and combined in terrorist training camps, but not once they are on the board.
We play all cities count as a liberation point regardless of where they are, we also play that while in training camps terrorists can exist in any form they want so rather than having 20 vanguards in your camp you could just have 2 cells to save on the pieces. Once on the board terrorists can be added to but not partially. You have to make it go to the next complete level or any extras are wasted i.e. if using the terrorist recruitment card and adding a column to a country containing a vanguard you must either pay the extra 40m to make it a cell or discard the vanguard. This stops there being 4 vanguards in a country as someone couldnt afford to make it a column etc
