Swallow
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
A swallow is an decoy drone used to lure enemy heat-seeking missiles away from a Colonial vessel.
These devices were deployed from Raptor 478 to successfully lure away two missiles shot at it by a Cylon Raider during the Fall of the Twelve Colonies (Miniseries).
Enough swallows can mimic the electrical "footprint," or signatures of other spacecraft, even that of battlestars when programmed and grouped together (Exodus, Part II).
Raptor pilots deploys swallow and other ECM devices by commends to their ECOs.
