Advanced Squad Control (Simple) addon

This is a mod that will increase the number of squads from the vanilla four to either eight or ten.

Extract to your Army Men RTS root directory.
First, download the 7zip file. Then choose which 7zip self-extractor to install. It is recommended to only use eight squads if you play at 640x480 resolution.

You can use the 5 - 8 keys alone or in conjunction with the Shift, Control, and Alt keys like the original 4 squads.

You can press the tilde key ( ` / ~ ) to remove units from the squad they are in.

You can also press the 'A' key to order a unit to attack an object.

You can press the 'H' key in conjunction with the Shift key to jump to your Hero units (assuming you have one).
You can press the 'Delete' key to order a building to recycle.

When installing the Ten Squads version, all the above keys will still apply. In addition, you will gain two additional squads which can be accessed with the 9 and 0 keys respectively.
