Currently, when you copy a unit and paste it onto the map, it will simply copy the unit class. Creating a custom squad of, for example, PMCs would be a nightmare. I would have to remote-control and individually equip them.
Instead of copying the unit class of units, it would be nice if when you copied selected units, their current load-outs would also be copied so that you can easily and quickly custom-equip a plethora of units on the fly.
Otherwise, you're stuck using remote-control to outfit every one, which can be extremely time consuming if you need to make any more than 2 units, hardly making it worth the effort.
