There are conflicting experiences about how important a small profile is. The very low profile German Stug III was greatly feared by Soviet tankers as it was a very good vehicle which heavy armor in front and a powerful cannon which chould be camouflaged with relative ease. Desert Storm seems to indicate that at least in large open spaces a small profile is not overly effective to protect a tank against accurate weapons with excellent optics, an experienced mirrored by ex-tankers (Waylander?) on this board.The profile of the vehicle seems to be a little to big though, dont you think? It would make a nice large target. In Indian army they made a big fuss about the taller profile of Arjun MBT compared to russian equivalents(they are still making a fuss ). though Arjun's profile is closer to most western tank designs I am told. u.
Personally I think that the - considering it's role rather small - tradeoffs of the Terrex 's taller profile is outweigh by the advantages of greater protection against mines and IEDs and more space.
