Oplan HACKLE was a supposed plot by rebel soldiers in the Philippines to overthrow the Arroyo administration, foiled by the Armed Forces of the Philippines (AFP) on February 24, 2006 (see Philippines under state of emergency, 2006). Allegedly, the four-phase plot included a mass jailbreak of Magdalo mutineers and the unfolding of anti-government posters during a Philippine Military Academy reunion.
The rebel Magdalo soldiers are said to be working with the New People's Army, a communist military organization - The AFP claims "HACKLE" is an abbreviated form of "hammer and sickle".
