My guess would be it is mostly intended as an internal security vehicle
Otokar is positioning the Akrep II as a possible successor for its previous line of Akrep I vehicles. The Akrep I, which did in fact use automotive components from the HMMWV, is more commonly known as the Otokar Cobra and (modernized, rebuilt) Cobra II.
Turkey, Nigeria, Pakistan and Bangladesh as the main users of the Cobra all use them for internal security for the most part. The only somewhat symmetric uses were in the South Ossetia War by Georgia and in its invasion of Syria by Turkey, usually in recon or heavy infantry weapon carrier roles. There are videos from such operations showing them surviving RPG hits, though realistically they're about comparable in performance in that regard to e.g. French VBLs or German/Dutch Fenneks (which also have comparable large-sized windows btw).
is it just me or are a lot of these lighter armored vehicles built roomier? Looking at how much interior space there is from those windshields, compared to the armored HMMWV. Then again, a lot of it might be taken up by that turret's hardware, so...maybe not?
Interior of the Akrep II mockup, a bit too clean of course:
Turret is presumably meant to be self-contained and remote-controlled, it's not like it'd really sell otherwise. Outer frame of the vehicle is rather comparable in size to a Cobra II.
The rather more realistic actual Cobra II is rather roomy for its purpose too (... it also weighs twice as much as a uparmored M1114 HMMWV). This is the infantry mobility version - two canvas seats for driver and commander to the right, center seat for gunner flipped forward to stand on, two benches in the back for three people sitting on each side:
