| NOTES |
1The model year provided here was not used by
the Soviets but it serves to distinguish this tank from the original version of the BT-5
which used a modified BT-2 turret.
2This estimate is based on an analysis of BT
series production and Soviet tank production statistics.
3With/without radio equipment installed.
4The data refers to operation
of the vehicle on tracks (wheels). |
