You have many variants of the Patria same with the sisu norway/finnland etc use.. The norwegian sisus that are in use in afghanistan are uparmoured, but some of the still have propllers but wont have the same floating ability as the original onedtacs wrote:I'd have to ask you for a source on that.

The AMV is offered in three main variants: a basic platform, a high roof platform and a heavy weapon platform.
* The AMV basic platform includes APC, IFV, C2, ambulance, reconnaissance, mortar carrier, FCV, ATGM and MGS vehicles. Basic platform can also be provided as an extended Basic L platform with increased internal volume.
* The AMV high roof platform features a larger and higher rear compartment which allows more space-requiring work to be done inside the vehicle. The AMV SP is suitable for e.g. C3, large ambulance and workshop vehicles.
* The AMV heavy weapon platform features stronger structure enabling heavy weapon systems e.g. Patria AMOS 120 mm mortar turret or Mobile Gun System
