did pike blocks really just fight with two ranks?

[pike master]

did they? i always read they fought with 4 to 5 ranks deep.

i wonder why CA decided to go with two? i suppose i need to go back to the books and recheck my sources.

i found this picture showing some reenactors with their pikes presented. i looks to me like most of those guys are gettin ready to bust a gut open 8). the only i see thats not straining is a big giant of a man in the middle whos wandering why everone is having so much trouble holding their pikes up.

if those things were that massive i dont see how you could fight offensively with them. surely the ones that you would fight with were shorter and lighter than 21 feet.

but as you can see there are only two ranks lowered.
