How does the Red Police choose the same arms?

Press one or more American soldiers or other soldiers or tanks by T. Press 1 and tanks. It is to select all the same soldiers under the current screen. Press 2 to select all the arms you train/manufacture.

Why do red police officers buy 100 soldiers in one click?

Press Shift while clicking on the icon. When you want to build a large number of tanks or infantry, you can hold down the shift and click the unit you want to produce. This way, click to click on 7 units that are equivalent to automatic production. If the barracks are built more, the production soldiers will quickly remember the method. Then five or six are five or six. The barracks are almost the same.
