Even though communication is important on modern battlefields, it is curiously absent from JA2. So I implemented a new minor trait: radio operator.
A radio operator is a soldier that has received communication equipment training. Only radio operators can use such equipment, in this case radio sets. A radio set (item #1697) is worn like a backpack and requires special batteries (item #1698) on order to work. With such equipment, an operator has access to a variety of unique skills.
These skills are called by pressing $ in tactical – which calls the new skill menu – and then selecting the correct skill (currently usable ones are green). As some skills require a target location, the location your mouse was when you opened the menu is taken for this and is coloured green while the menu is active.
