M113s can have Alkar mortar to give indirect fire support to keep them further away so it would matter less, for example. Cheap and could still have something to do. It is better than just letting them sit in reserve as they are, which is most certainly what we are going to do if we ever pick a replacement.Honestly, M113 is paper thin as opposed to this one. Modernised ZMA-15 has add-on armour on sides and ZMA-X is almost the same thing, plus the unmanned control and LIDARs
