Hello,today my friend Pegasus told me about this bug,i tried it 3 times and it actually worked.First when u get into an interior u do /dropweapon and drop ur parachute and after that if u have any grenades or molotovs they become equipable and u can equip them and throw them in the interior but it doesnt take any damage.This must be some kind of bug.
