Another technical thread now.
Just how advanced a military could Britain have fielded in 1939?
I'm not just talking about well euipped here, but rather how high tech a force could Britain have built based on available resources between 1918 and 1939.
For the purposes of this thread we'll suppose that Britain siezes on every discovery that had military potential between the wars and develops it has far as they can, as efficiently as they can.
What could they have come up with?
