True, which is why the 2-1 odds on the offensive would presumably be necessary; certainly being able to sustain 3 divisions/9 brigades against the Axis mobile forces is more likely to create success than the (historical) 1-1 was, generally.
On the defensive, of course, it's another situation entirely for the British et al.
Best,
I'm wondering what would have been possible by the OTL British forces given a modicum of luck and perhaps better command and command decisions. For example Britain was caught short twice, after Compass and Crusader, by Rommel's early/premature recon in force turning into successful offensives. Surely these could have been avoided given the forces at Britain's disposal and different deployment.
