Dalek army
The "Dalek army" referred to the gathered forces of the Dalek race, (TV: Resurrection of the Daleks) typically when discussing their ground forces. (TV: Planet of the Daleks, et. al) However, the ability for Daleks to operate in atmospheres (TV: The Stolen Earth) and space through flight meant a "Dalek army" could do more than simply attack on ground. (TV: The Parting of the Ways) The Dalek army could thus besiege and attack locations in space, in atmospheres, and on ground, (TV: The Parting of the Ways, The Stolen Earth) attacking targets by flying above or landing on the ground. (TV: Doomsday)
During a Dalek invasion, the Dalek army would work alongside the Dalek Fleet, with Daleks operating in the fleet easily joining the "army" unit if the attack called for it. (TV: The Parting of the Ways, Revolution of the Daleks) Being a warrior race totally focused on conquest and extermination, (TV: The Witch's Familiar, et. al) every individual Dalek was part of the overall Dalek army, even if that specific Dalek was currently operating aboard a warship of the Dalek Fleet branch. (TV: Resurrection of the Daleks, et. al) Despite therefore being part of the army and holding a command position within it, various Dalek officers, such as Supreme Daleks, would not see active combat and instead commanded away from the frontline.

History
The Dalek Empire named its overall army branch the Imperial Dalek Army. (COMIC: Emperor of the Daleks!) The New Dalek Paradigm and Resurrected Dalek Empire called their overall army the Dalek Imperial Army. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) Upon taking control of Defence Drone casings, Dalek mutants created from human DNA heralded themselves as the "New Dalek Army", only to be exterminated by a Dalek Death Squad which the Thirteenth Doctor had lured to Earth.
