What do these symbols mean in Storm of Arrows?

Portalble Defenses (buy them and place them somehow)(right-clicking on unit on battlefield I think)

S = dismounted option...hover cursor over the S in the DAG screen to show dismounted option.

You actually dont have to hover over the S, anywhere on that unit line will cause it to change the stats to the dismounted version(kind of disconcerting until you get used to it)
