Enter the "Unit Editor" option at the main menu and create a configuration file. Name it whatever desired, then edit the troops, building, tanks, or turrets that you want to make stronger. Next, go to a multi-player game and select "Solo Play" to host the game. You should then see a option that reads "Unit Stats". Select it until the name of the configuration file that you created appears. Set the game up and quit after about one minute of game play. Go back to the main menu and enter a single player game. Choose the level you want to play. If done correctly, the unit stats should be active.
