Its name starts with "BLD_Humans_Dungeon_2_A_5H_Wall_5_A" because it looks exactly like the wall with the same name. However, walls cannot be moved, cannot be destroyed, or otherwise interacted with. So if you want to have a secret moving wall, or a wall that can be destroyed, or that does something else, you need an item that looks like a wall, but in practice is a dynamic item.
So if you just want a wall, you should use the wall editor and place that particular kind of wall.
If you want this particular wall object because it should move or so, there are two ways to make it not see-through/shoot-through:
* in its properties, deselect the see-through and shoot-through properties. I'm not sure why they are enabled in the first place
* at the same location as the wall object, place an invisible blocker helper (Helper_Blocker_A or something like that; search for helper or blocker among the root templates, and enable the visualisation of the physics layouts so you can see how big an area it blocks)
