Signals, Calls, and Marches is an EP and the debut release by American post-punk band Mission of Burma.

The album's first track is "That's When I Reach for My Revolver," which features a singable, anthemic chorus that helped make it one of the band's most popular songs.

"[3] Guitarist Roger Miller noted that the sound probably helped the band become more accessible, recalling: We played a show in Cleveland ('81 or '82) and we were on the street in front of the club.

In his retrospective review, Mark Deming of AllMusic stated that "if Mission of Burma were not yet at the peak of their form, most bands blazing as many trails as this one did lost their footing a lot more often that Burma did on these six songs; Signals, Calls and Marches was as accomplished and impressive a debut as any American band would release in the 1980s.

Mark Deming of AllMusic wrote, "One could argue that [Signals, Calls, and Marches] was the point where indie rock as a separate and distinct musical subgenre well and truly began.
