Stridsvagen 103 (STRV 103) also known as the S Tank. Swedish main battle tank.
I am saying Bovington as the British Army tested two from memory against the Chieftain and the results were quite favourable for the S Tank.
Strdsvagen 103 - the fames S-Tank which I thought was the "coolest tank ever" as a lad in the 70's building 1/35th Tamiya plastic model kits. The particular vehicle is located in a cinderblock building that features good natural light sources.
Swedish S-tank. Just when you thought assault guns went out of fashion after WWII ended . . .
Swedish S-Tank! Never seen one 'in the flesh'.
Neither have I. Looks like a cross between a Hetzer and a STUG III.
