Under "Turn Sequence": "calalry" should probably be "cavalry", "a players turn" s/b "a player's turn", looks like you have an extra space between "all" and "of his flipped".

Under "Movement": "You many move" s/b "You may move", missed capitalizing "flipped" at start of sentence.

Under "Attack": "is equal or greater than" s/b "is equal to or greater than","the the target" s/b "the target" or maybe "then the target", remove period before "(choice of defender)", "The" in "If The target unit" should not be capitalized.

Under "Special rules": capitalize "rules" in section title for consistency, "Only" should not be capitalized.

Standardize to spelling either "defense" or "defence".
