There is no way to unequip your officers by design. The thinking is that once you hand over any sort of weapon or good, it is a gift and your officers can make their own decision. If you would like to change that in your game, find script file: Program\INTERFACE\items.c. Find this function:

void SetVariable()

Within that function, change the lines in the “else” block to this:

else
{
	//SetNodeUsing("EQUIP_BUTTON" , false);
	SetNodeUsing("EXCHANGE_BUTTON" , false); //bExchg);
}

The console is enabled and you can execute with F4 if you want to use valid script code like that link.

To remove all equipment, but leave it in their inventory, use the following:

void ExecuteConsole()
{
    ref eqchar = GetCharacter(sti(pchar.Fellows.Passengers.doctor));
    //For fighters, use id1 - id6 
    //eqchar = GetCharacter(sti(pchar.Fellows.Passengers.Officers.id1));
    RemoveCharacterEquip(eqchar, GUN_ITEM_TYPE);  //Removes any gun
    RemoveCharacterEquip(eqchar, BLADE_ITEM_TYPE); //Removes any sword
    RemoveCharacterEquip(eqchar, CIRASS_ITEM_TYPE); //Removes armor or special clothing item
    RemoveCharacterEquip(eqchar, HEAD_ITEM_TYPE); //Removes hat/helmet
}

Oh, also keep in mind that the officers will always sift through their inventory every time you give them something, so even if you equip them with something particular, the very next time you place something in their inventory/trade with them, they will requip themselves with what they consider to be the best items again in all categories. Even if you give them a bandage, they may decide to change their gun, blade, or armor from what they have in their possession.

I think also if you give them a new perk, they will decide again…I can’t remember if I also added that event…
