Dogs of War: defensive structures and personal / supply for squads

[Dogs of War: defensive structures and personal / supply for squads]

Hi!

Well, i actually have 2 questions about the mission dogs of war (Söldner):

1. (iportant) one: how do i build defensive structures with soldiers on them?

i tried to buy soldiers myself, command them to board the building and then i told them to leave my squad, but this causes a stupid situation:

When another squad gets destroyed, the soldiers on the turret will be the new squad leader and doesnt want to move at all :(

2. Do the squads care for new supplies (fuel, ammunition, vehicles and soldiers) for themselves or do i have to take care for them?

Thanks,

Joe
