The Object 187 explosive reactive armour is Malahit, The T-14 reactive armour is Malachit, Is this a typo on the Object 187 web page or are there two Russian M named reactive armour vehicles Malahit and Malachit?
As fare as I know Relikt is a cheaper downgraded version of Malahit or is it Malachit?, And yes you are correct Mike E the T-14 does not need reactive armour with active protection system Afghanit.
T-14 features an active protection system Afghanit (Russian: Афганит). This system includes a millimeter-wavelength radar to detect, track and intercept incoming anti-tank munitions, both kinetic energy penetrators and tandem-charges.[2][35] Currently, the maximum speed of the interceptable target is 1,700 m/s.
