hf43.0.5より一部抜粋

Steel Path Railjack missions now drop MK IV Railjack Turrets as part of the mission drop tables. These MK IV variants of Railjack Turrets are around 50% more powerful than their MK III versions, and come in every House except Sigma (as this house is Research exclusive).
Steel Path Railjack drop tables have been adjusted to add these new Turrets —  including the removal of MK I and II Components and Armaments from enemy droptables. Check our drop table site for the full array of changes.
Only Railjack Turrets are getting the MK IV upgrade with this hotfix — we’ll revisit the need for Ordnances and Components in the future.

鋼でタレットの4が出るようになった　鋼では1と2の兵装が出ないようになった　今はタレットの4しかないがいずれ他の装備も追加する　逆に今の時期はタレットを狙って鍛えやすいのかもしれない　公式ドロップテーブルはこれを書いている時点ではまだ更新されていない
