Ah... I want to try historical pikes and shots in M2:TW. By not succeed because of buggy shot" (gun units).

Pike and Shots - Historical Description: Pike men form a square and the gunners screen the pike square and shoot until the enemy is reaching them. Then retreat back to the pike square for protection.

Can you make it work... The gunners rotate the lines to fire enemies from their sides, thus leaving some of them unprotected outside the walls of pikes.
