Thanks to Damian for the link!
Defense Studies Blog has the latest on the BT-3F and its worth a read. I find this vehicle interesting. Its suppose to be the amphibious ride for Russia and its allies and I'm looking forward to seeing how it performs. If I recall correctly this is the first purpose built amphibious assault vehicle they've tried to build. Most of their IFV/APCs are swim capable but this supposedly will be a different kettle of fish.
