"Brothers in Arms" is a 1985 song by Dire Straits, appearing as the last track on the album of the same name. It is in G# minor. It peaked at #16 in the UK.

There are actually two studio recorded versions of this song: the album version which is 6:55 seconds, and the shorter version which is 6:05 seconds and features slightly different (and shorter) solos at the beginning and end of the song. The version that appears on Dire Straits' greatest hits album, The Very Best of Dire Straits, is 4:55. The version featured on the live album On the Night contains an extra slide guitar solo and is 8:55.

Mark Knopfler usually played the song on a Gibson Les Paul guitar, rather than his usual Schecter "Stratocaster", and a Les Paul appears in the distinctive promo video, which is in the style of a charcoal drawing, interspersing scenes of the band playing with scenes of war. During Dire Straits' 1992 On Every Street tour, Knopfler used his Pensa Suhr MK1 for this song, like most of the others.
