A two year engagement through a sector of space claimed by the remnants of the broken Eldar race, the Scalland Campaign was to serve as the original field test for the first thousand sets of prototype armour that would later come to be designated as MkVI; though at the time it bore the provisional designation MkV. Small numbers of the MkV armour had already been submitted to the Iron Warriors and Salamanders Legions, and both had expressed reservations about the lack of heavy plating when compared to earlier marks, pushing for the MkV to be revised for a heavy assault role. It was deemed that a mass combat trial was required to determine the effectiveness of the original design before potentially abandoning it .Internal politics within the various Legion commands saw this honour bestowed upon the Raven Guard, depleted in number after the bloody fighting in the Akum-Sothos Cluster. Speculation at the time suggests that a faction amongst the Primarchs and Legion commanders, led by Perturabo, intended this assignment to an under-strength Legion to be the death-knell of the MkVI armour, leading to its replacement by a sturdier design.

Scalland戰(zhàn)役交戰(zhàn)時(shí)長(zhǎng)兩年，戰(zhàn)場(chǎng)星區(qū)是一片被分崩離析的古老艾爾達(dá)種族殘民聲稱(chēng)為其所有的空間，這次戰(zhàn)役對(duì)于最初的一千套在之后設(shè)計(jì)為MK6型的動(dòng)力甲原型機(jī)進(jìn)行了初始戰(zhàn)場(chǎng)測(cè)試，不過(guò)在當(dāng)時(shí)它的臨時(shí)稱(chēng)呼MkV型動(dòng)力甲。少量的MkV型動(dòng)力甲已經(jīng)被交付給了鋼鐵勇士和火蜥蜴軍團(tuán)，兩者都對(duì)這種相較于早期型號(hào)動(dòng)力甲而言缺乏厚重板甲的新型號(hào)持保留意見(jiàn)，他們推動(dòng)了對(duì)Mk5動(dòng)力甲的修改工作以使其承擔(dān)重要進(jìn)攻任務(wù)。（不過(guò)）帝國(guó)認(rèn)為在可能性地放棄這種初始（新）型號(hào)動(dòng)力甲之前，要用大規(guī)模的戰(zhàn)斗試驗(yàn)來(lái)決定其（戰(zhàn)斗）效率。各個(gè)帝國(guó)指揮部的內(nèi)部勾心斗角見(jiàn)證了這份榮譽(yù)被授予了暗鴉守衛(wèi)軍團(tuán)——他們?cè)贏kum-Sothos群星的血腥戰(zhàn)斗之后人數(shù)銳減。當(dāng)時(shí)的推測(cè)表明：在原體和軍團(tuán)指揮官中間有著一個(gè)由佩圖拉博領(lǐng)導(dǎo)的派系，他們打算將這一任務(wù)指派給某個(gè)力量薄弱的軍團(tuán)，以此為Mk5型動(dòng)力甲敲響喪鐘，為的是用某種更為堅(jiān)固的設(shè)計(jì)將其取代。（機(jī)仆：老皮玩政治，真是夭壽了活久見(jiàn)…）

If this was so then the plan was to backfire spectacularly, for the Raven Guard performed admirably in the verdant Eldar seed worlds of the Scalland Sector, utilising the advanced auto-senses and agility of the new armour to hound the Eldar in a series of strike-and-fade attacks that decimated their already battered military forces. Such was the success of the fighting in the sector, which eventually saw the expulsion of the Eldar and the Imperium claim its rich worlds, that not only was the MkVI armour approved for final development, but the majority of the improvements suggested by the Raven Guard were adopted. The new armour, later dubbed 'Corvus' armour in honour of the Raven Guard, was placed into full scale production only a few months before the outbreak of Horus' rebellion against the Emperor, re-designated as MkVI to account for the inclusion of the many stop-gap field modifications and repairs into the Legiones?order of battle.?
