[Mobhack]

The L-D sequence is written for transports (APCs and Trucks and probably helos etc) as far as I recall, though it MAY work for a platoon that has say 2 tanks and 2 rifle sections in it. Try an experimental formation in Mobhack and see if it works?.

As for the load all key - Game Guide, "Deployment Menu", scroll down a bit to the list of hot keys and see the section for "D". There is also a button for this - see the pic slightly above the "range Set" sectio with the landing craft etc - the button with 2 tanks and a "D" on it, middle of the second row from the bottom.

Cheers
