File (formation)

Troops from the U.S. and Bangladesh March in single file during a tactical training exercise during 2014.

A file is a military term for a number of troops drawn up in line ahead, i.e. one behind the other in a column. The number of files is the measure of the width of a formation of troops in several ranks one behind the other.^[1][2][3][4]

Usage

Files are useful when troops don't know where the enemy is, since there are overlapping fields of fire from each soldier, and cover from a possible flanking attack. Files are at a disadvantage when there are heavy weapons nearby, supported by infantry, especially machine guns and tanks.^[1][2]

Ancient Greek use

A file of men in the Greek phalanx was called a lochos (Greek: λόχος) and usually ranged from eight to sixteen men.^[2][5][6]
