Which statement about the Mexican army is correct in the years from 1829-1835? It is corrupt. The best example is at the battle of Mission Concepcion when the gun powder was so ineffectual that bullets bounced off of the Texian rebels. It is political. Most of the officers in the Mexican Army actively support one faction or another in the political system, and they aren't opposed to calling out their armies against their opponents. Its officers are incompetent. Again and again, the officers of the Mexican army are unwilling or unable to effectively organize the army by the modern standards of the day. All are true statements.
