Battalion

A battalion is a military unit. The use of the term "battalion" varies by nationality and branch of service. Typically a battalion consists of 300 to 800 soldiers and is divided into a number of companies. A battalion is typically commanded by a lieutenant colonel. In some countries the word "battalion" is associated with the infantry.

The term was first used in Italian as battaglione no later than the 16th century. It derived from the Italian word for battle, battaglia. The first use of battalion in English was in the 1580s, and the first use to mean "part of a regiment" is from 1708.

Independent operations

A battalion may be the smallest military organization capable of independent operations, though this depends on the definition of "independent operations". It must have a source of re-supply to sustain operations for more than several days. In addition to comprising sufficient personnel and equipment (usually at least two primary mission companies and one mission support company) to perform significant operations, as well as a limited self-contained administrative and logistics capability, the commander is provided with a full-time staff whose function is to coordinate current operations and plan future operations. A battalion's subordinate units (companies and their organic platoons) are dependent upon the battalion headquarters for command, control, communications, and intelligence and the battalion's organic service and support structure to perform their mission. The battalion is usually part of a regiment, brigade, or group, depending on the organizational model used by that service. Battalions generally can operate for no greater than 10 days without higher echelon support, and are unable to operate away from a supported location without their higher headquarters regiment, brigade, or group's logistical support structure.

Metal Church

Metal Church is an American heavy metal band. They originally formed in San Francisco, California in 1980 before relocating to Aberdeen, Washington the following year and briefly using the name Shrapnel. Their eponymous debut album was released in 1984, and their latest, XI, is due for release in 2016.

The band is credited as a formative influence on the thrash metal subgenre, melding the aesthetics of the New Wave of British Heavy Metal and American hard rock with "incredibly tight musicianship" and "piercingly screeched" vocals. Early lyrical topics such as conflict and paranoia later expanded into philosophical and social commentary.

Founding guitarist Kurdt Vanderhoof remained the group's sole consistent creative force throughout its career, despite reducing his role strictly to composition in 1986 after tiring of performing. Vanderhoof, vocalist David Wayne, guitarist Craig Wells, bassist Duke Erickson, and drummer Kirk Arrington composed the group's classic lineup featured on its first two records, while vocalist Mike Howe and guitarist John Marshall later contributed to the group's sound. After releasing five full-length albums and touring extensively throughout the 1980s and early 1990s, Metal Church disbanded in 1994. They reformed four years later with their classic lineup, including Vanderhoof's return to performance, yielding the Masterpeace album. They endured numerous lineup changes thereafter, releasing three further studio albums while fronted by Ronny Munroe before again disbanding in July 2009. The group once again reunited in October 2012 and released Generation Nothing a year later. Following Munroe's departure in the fall of 2014, Howe rejoined Metal Church in April 2015 at Vanderhoof's request, and recorded their upcoming eleventh studio album XI.

Blind Guardian

Blind Guardian is a German power metal band formed in the mid-1980s in Krefeld, West Germany. They are often credited as one of the seminal and most influential bands in the power metal and speed metal subgenres. Ten musicians have been a part of the band's line-up in its history, which has consisted of singer Hansi Kürsch, guitarists André Olbrich and Marcus Siepen, and drummer Frederik Ehmke since 2005.

Blind Guardian is a part of the German heavy metal scene that emerged in the mid-1980s. The band was formed in 1984 as Lucifer's Heritage by Kürsch (then also bass guitarist), Olbrich, other guitarist Markus Dörk and drummer Thomas Stauch. Dörk and Stauch both left the following year, and were replaced by Christof Theißen and Hans-Peter Frey respectively, who left as well before the end of the year. In 1987, Siepen joined and Stauch returned; under this line-up, which lasted 18 years (the longest in the band's history), the band changed their name to Blind Guardian and released their first album, Battalions of Fear, in 1988.
