That’s it all of you should start playing World of Tanks!!!
If one is to go about recreating a WWII era tank train then the ones in the photo look to be M2 Light tanks. Something that was never used in combat and only for training. Vehicles actually used in combat include:
M3 Lee
M4 Sherman and its many variants.
M3 Stewart Light tank
M26 Pershing though this was late in the war.
M18 Hellcat
M10 Wolverine
M36 Jackson
M24 Chaffee late in the war
M3 Half track
M7 Priest artillery
CCKW Transport
DUKW
And of course the Jeep
