Flyer Scar:

Flyers now automatically fall back to their designated point of origin or nearest building of the designated type. This is still in the early stages of development so expect bugs and dysfunctional behavior but when it works as intended it makes flyers an entirely new element of game play in that they have to be managed in different fashion than other units, with multiple point plotted routes being the standard method of employment.

Destructible Terrain:

Destructible objects on a given map are neutral entities until a player (ai or human) has an entity within a predetermined range of it.

Once they have an ebps in that range the NEUTRAL entity becomes possession of the player, making it target-able by enemy players and thus destructible (yes you can even delete it like you would one of your own buildings),

And finally once you have no ebps entities within X distance of a given map entity it reverts back to neutral state making it "claimable" by another army.

Defensive Placements:

Tank Traps: Stop/Slow and damage vehicles that hit them, can be camouflaged

Razor-Wire: Stops/Slows infantry, does minor damage and reveals stealthed units, can be camouflaged

Sandbags: Provide damage reduction, small chance of not being hit and a heavy cover bonus

Shield Generators: Repel most enemy fire and keeps enemies from moving into the shielded area.

Walls: Large redoubts common to such forces as the Iron Warriors and Imperial Fists, Walls not only provide excellent protection but help the defender dictate enemy troop movements.

Trenches: Dug in defensive lines that provide fantastic defense against artillery to nearby infantry units and also provide said infantry with a tremendous advantage vs. approaching enemy infantry.  The best infantry counter to this is using melee specialists+teleportation/droppod/jump packs/etc; to get right into the trench and get to grips with the infantry hiding there. 
One final note, moment of infantry (both allied and foe)  is slower than normal while in trenches.
