Good evening.
Thanks Eswube and Odysseus for the feedback! (and yes, 2S7 is coming!, but I want to end some french made vehicles first!).
This is the cuban armoured FSV BTR-100, it was built matching the hull of an old BTR-60, with a diesel engine and a lightened T-55 tank turret, complete with D10 100 mm gun. First seen in 2011, this one is depicted as seen at Havana during 2014 military parade.
Shading: I don´t know if the shading of the turret and hull is correct. The angle of the picture was quite different to the lateral view. I will welcome any comment.
Credits: Thanks to one of our experts in russian/soviet materiel: Caddaric 79, because he is the author of the BTR-60PB that I used as starting line. Cheers.
Edited for correcting the credits.
