The 2nd, 3rd, 4th and 5th Companies are known as '''Battle Companies''', as they generally form the main battle force deployed for engagements. All four Companies have the same organisation, split into 6 '''[[Battleline SquadsSquad]]s''' which consist of [[Tactical Squad|Tactical]] and [[Intercessor Squad|Intercessor]] formations, 2 '''[[Close Combat SquadsSquad]]s''' which consist of [[Assault Squad|Assault]], [[Reiver Squad|Reiver]], and [[Inceptor Squad|Inceptor]] formations, and 2 '''[[Fire Support SquadsSquad]]s''' which consist of [[Devastator Squad|Devastator]], [[Hellblaster Squad|Hellblaster]], or [[Aggressor Squad|Aggressor]] formations. Each Battle Company also includes around two [[Dreadnought]]s, and maintains their own motor pool of [[Rhino]], [[Impulsor]]s, and [[Razorback]] transports, [[Land Speeder]]s and [[Space Marine Bike]]s.{{Fn|5}}
