A few interesting vehicles in here...what is that two turret tank?

M2E2 Light Tank. The second turret was added to house an additional machine gun to increase firepower.
An idea that proved to be a blind alley as regards AFVs but may have influenced design of defensive armament on some models of WW2 LVTs which had a gun mounted either side toward the front within a semi-circular housing/shield.

Dave,

I think, at minute 2.45, it's an M2A3 light tank - twin turret, angular hexagonal cupola (or an M2A3E1 if equipped with a Guiberson radial diesel). The predecessor, the M2A2, had a rounded cupola. I think there is a brief glimpse of an M2A2 (or M2A2E1 if powered by a Guiberson radial diesel) at around minute 3:27, but the majority of footage is the M2A3 with the hex cupola.

As you rightly say, a blind alley when it comes to tank development.

Thanks Mike, the info I have is rather skimpy and doesn't delve into all the variations. I was counting on someone correcting me if needed and anticipated that Hanno may have had something to say as he seems to have an interest in early tanks.
