Mobile Medical Suite

This was a request by Wolverine for a drawing of a Mobile Medical Suite. At first, I thought it was a ATOC drop ship. Then I thought it was a converted AT-TE or a troop transport. Upon seeing 'Floating Fortress' (which I could not find anywhere on web) I happened on the 'Floating Fortress' by Khairul Hisham - too bad I was ready to do a converted B-17 :)
There is an elevator on top with four observable graple points. I placed the turrets on alternate sides front and rear to get a better arc of fire (H2O in this case). The droid and observing crewmember are shown for scale.
I was wondering what the Star Wars world would use for a medical symbol? So I just made sure vehicle was highly observable with the self illuminating red bands.
