El Alamein's "I Get Pissed Off When You Spell My Name Wrong" Edges:

 Main Guns: 6-Pounder  vs. 75 mm:  Uh... I have no idea where to find information on these weapons - give me a link and I'll give you an edge.

Edge: N/A

 Machine Guns: Lewis vs. Hotchkiss:  The Hotchkiss is a lot heavier but that doesn't matter when it's mounted on a vehicle - but its 8mm Lebel round is simply another machinegun round - the Lewis' .303 British cartridge is an armor-piercing bullet. The Lewis has a higher rate of fire (500-600 rds/min against the Hotchkiss' 450 rds/min), but the Hotchkiss can take a 250-round belt while the Lewis can only take a 47-round drum - however, such an early form of a belt-fed MG is prone to jamming. The Lewis wins this one thanks to its heavier round, faster rate of fire and more reliable firing system.

Edge: Mark IV Tank

 Armor:  The Mark IV has a little bit more armor, so it's gonna offer more protection.

Edge: Mark IV Tank

WINNER: N/A

I'm going to need to compare the main gun before I give either tank a winning edge.
