Return fire while hands disabled

When my unit attacks an enemy with rifle(required both hand to use) and return fire ability, i shoot to one of his arms and disable it but then this enemy return fire to my unit. Once i had mission where an enemy with disabled both hands returned fire to my unit.

What enemy? I’ve disabled the arm on many enemies specifically to prevent return fire. Tritons are tricky because they have four arms you have to be very specific with which arms you hit to disable their weapon.

other factions… Humans.
