Yes and no not really. Historically, W3D is not good with textures applied to high resolution meshes (if I remember correctly), but with more modern hardware, we can afford to throw the boat out a bit more on quality. Last time I looked, the typical infantry character in AR tends to have nearly double the polygons of the best looking infantry character in Reborn.
To support what the other guys have said, I'll just quickly run through building objects in an easy-to-follow list.
Purchase Terminal - Buy your Infantry and Vehicles here.
Repair Node - Engineers and Technicians can use their tools on this object for a faster repair rate. The advantage of these nodes is that Engineers can repair the building safely without being gunned down by SEALs that are camping the Major Weakpoint/MCT.
Minor Weakpoint - Easy to Kill, disables the building until it is repaired.
Major Weakpoint - Hard to Kill, the building is destroyed when this is destroyed, much like MCTs in Renegade/APB/Reborn.
