One weekend a month, two weeks a year
"One weekend a month, two weeks a year" is a former recruiting slogan used by the U.S. Army National Guard. It indicated the amount of time an individual would need to spend actively in the Guard to be a Guardsman with benefits. It was dropped during the Iraq War after it became clear that Guardsmen were now serving considerably more time in service.
Usage of the slogan
The slogan "one weekend a month, two weeks a year" has been most commonly seen by Americans in recruiting ads for the National Guard. Although the slogan is only sometimes used directly in advertising, as of 2004[update] it was used to describe the duties of at least some military posts. 
The slogan has also been used to contrast the commitment that a National Guard member would give during those times when his country was not at war. Other forces have used this slogan as something against which they can contrast their own dedication,  showing that, as members of the special forces, they are not mere "weekend warriors".
Understanding among the enlisted
Understanding the meaning of the slogan to those enlisted in the National Guard requires understanding the historical context in which it was given. During World War II, the National Guard was called up to defend their country, and this was repeated in the Korean War even when American soil was not directly threatened. At this time, joining a reserve component could clearly be seen as a route to service overseas. However, at the time of the Vietnam War, President Johnson made it clear that the National Guard's role was to defend the country and not to be involved in overseas adventures. At the time, this meant that those who joined the force could be fairly sure of not seeing action in the war.
These forces are expected to act as a second line of defense, primarily motivated by the fact that they are defending their own homes and families.
The commitment to Iraq and more recently, subsequent engagements, conflicts, and operations (primarily, and more specifically; those related to the Global War on Terrorism) has meant that many National Guards feel the terms in which they understood their recruitment have been breached. The slogan has now become known in a changed form, "One weekend a month, my ass,"  as a comment on the perceived mistreatment of the National Guard reservists.
Real service requirements contrasted to expectations
During some periods of the 2003 war in Iraq, the National guard represented 41% of the personnel deployed. The majority are supposed to serve for six months or a year. However, some specialists in the reserve forces have been required to serve for up to two years.
In the meantime, the role of the National Guard which, in the Vietnam War, largely revolved around home defense and policing,  has changed so that in Iraq "about 20 percent of the U.S. military deaths in that conflict"  have been carried by reserve and Guard units.
It has been claimed in the U.S. media that the change in expectations on the National Guard is a deliberate change in policy by military planners in response to the Vietnam War.  The need to use the National Guard is designed to reduce the possibility of "half-hearted" wars in future. Actual legal changes were made by the US Congress and in the 1980s which moved final decision from their commanders in chief, the state governors, to the federal government. These new laws were successfully defended against challenges from state governors in the U.S. Supreme Court. 
Army's future annual drill plans
In July 2012, the Army's top general, General Ray Odierno, indicated that he intends to change the National Guard's annual peacetime drilling commitment from two weeks per year to up to seven weeks per year, in addition to the weekend a month, which would not change. The changes come as the Army plans to reduce the number of full-time soldiers, and going forward relies increasingly on the Army National Guard. "How do we sustain the readiness and experience that we've gained in the National Guard and Reserve component?" Odierno asked. "That's what we've been working on." 
"One weekend a month, two weeks a year" was also formerly used as a descriptor in television advertisements for the Australian Army Reserve.
