Roster:
You cannot rely on the same 4-6 soldiers for every mission. Even if you keep them alive they will eventually get wounded and some wounds can take a long time to heal. Look to have a roster of between 10-12 veteran soldiers by using the early missions to give everyone in your squad experience and a specialisation.
Unlock Heroes:
At the 'Customisation' menu go to 'Character Info' menu and enter the following names (without the quotes) to unlock the corresponding hero. These cheats will only work in the Single-Player campaign and disables the ability to earn Achievements, they also remove ALL your previous soldiers' attributes. Note: Beaglerush must be put into the nickname field instead of the First and Last name like the other two.
Beaglerush (Grenadier):
Enter 'Beaglerush' (nickname).
Peter Van Hoorn (Assault Build Ranger Colonel):
