Armoured Platform "Models can be placed on top of this Model as if it were an Area of Terrain."
Models can move over and end a move on top of this Model, treating it as if it were an area of Terrain that grants a 5+ Cover Save to all Models on it. This Area of Terrain allows Line of Sight to be drawn into and out of its zone, but a Model outside that zone cannot draw a Line of Sight through the Area of Terrain to Models on the other side
Aegis Barricade "Any Model with the Infantry or Paragon Types that is in base contact with an Aegis Barricade gains a 5+ Cover Save."
Aegis Defence Line Barricades do not have any Characteristics and cannot be targeted, attacked, damaged or otherwise affected by any Rule or Weapon. Models can move through an Aegis Barricade and if they do move through such a Barricade must reduce the maximum distance that can be moved in that Move by 2" as if it was Difficult Terrain. Aegis Barricades do not block a Line of Sight drawn through them. Aegis Barricades must be Deployed so that at least one part of each Barricade is in contact with an Aegis Defence Line Core Platform or another Barricade – as long as one Barricade in any chain of Barricades is itself in contact with a Core Platform. All Models with the Infantry or Paragon Types that are in contact with a Barricade gains a 5+ Cover Save. The destruction of linked Aegis Core Platforms has no effect on Aegis Barricades, which remain in place.
