I have noticed that that the seventh menu ( Clicking 7 after selecting some of your soldiers) lacks the option associated with five ( 5 ) and goes from 1 to 9.
The option I suggest fits perfectly in this menu(The menu options could be reordered), adding these two options: (As it an option could be allocated in number zero ( 0 )
- Use silenced weapons
- Use non silenced weapons (OR any negation of the above.)
The first command should cause your subordinates to attach the silencer to their primary weapon if they have one, use their silenced secondary if not, or not shoot at all if they don't have any silenced weapon.
The second one should cause them to specifically REMOVE the silencer from their primary, assuming it had one.
