Understanding British Standard ORBAT
Posted: Thu Nov 21, 2013 9:59 am
Hopefully this will throw some insight on British Army ORBATs and allow designers to design some BR scenarios/campaigns using commonly seen formations on the battlefield. I’ll be using the Flashpoint Red Storm Battlefield tour data for the examples (for ease of use really and you will find slightly different OOB’s looking elsewhere as explained below).
First thing to note is that the Tank Rgt or Infantry Bn change over the years e.g. 3rd div/33 armd bde contained 1st Bn, Queen's Own Highlanders who were replaced by 3rd Bn Light Infantry in late 1989, the Bn org was the same, they took over the vehicles and other assets. So in any OOB source you may/will see slightly different Rgt/Bn.
However you need to look at the Bde org to see the formations not change that much over the years, again looking at 3rd Armoured Division you will see
4th Armoured Brigade consisting of 3 Tank Rgt and 1 Inf Bn
6th Armoured Brigade consisting of 1 Tank Rgt and 3 Inf Bn
33rd Armoured Brigade consisting of 1 Tank Rgt and 3 Inf Bn
See the pattern start to emerge, other brigades also sported a 2 Tank Rgt/2 Inf Bn or 2 tank Rgt/ 1 inf Bn setup, others may contain just 3 or 4 Inf Bn depending on the expected main task.
Flexibility is pretty much the order of the day, based on practical knowledge taken from WW2 experience of how the Germans operated in Kampfgruppen/battlegroups or Combined Combat Teams as US formations were called, so each Bde within divisions were nearly always organised to provide flexibility for the commanders depending on the tasks given by Corp or Division.
Now a Tank heavy Bde (3/1 or 2/2) would be considered offensive Bde or mobile reserve during defensive operations. Similarly an infantry heavy Bde (1/3 or 0/3) would be considered a defensive Bde or used as reserve formation during offensive operations.
Confused yet….dont worry you will be as we now look at Rgt/Bn sized formations i.e. Battlegroups (or Combat Teams if your US orientated). I will focus on armoured/mechanized formations here as an infantry only Bde is straight forward with the Bn’s operating as entire units, there are 2 main types of armoured/mechanized battlegroups used:
a. Tank lead – this was normally a 2/1 or 2/2 formation of 2 sqns of tanks and 1 or 2 companies of infantry under command of the Tank Rgt HQ.
b. Infantry lead – normally a 1//2 formation of 1 sqn of tanks and 2 companies of infantry under command of the infantry Bn HQ
You can carry on down to company sized battlegroups as above just replace sqn/company with troop/platoon, however these size groups were rare unless it was a small task i.e. capture/secure a bridge/rear area crossroad.
Support Assets
AD assets do seem to be missing, each Bde would get a battery of man portable Blowpipe/Javelin while Div would get a Rgt/Battery of Rapier tracked or mobile launchers.
These would normally be distributed down to the formations within each Div/Bde.
Corp support assets normally remained under Corp control and assigned to support Divisions depending on the task.
Division support assets – SPARTY – 3 Field Rgt per Division…oh 3 Bde per division…no prizes for guessing on the SOP split here. there were 2 Field Rgt of M109 (155mm) and 1 Rgt of Abbots (105mm), Bde commanders normally allocated this how they saw fit, however it was not unheard of to assign 2 Batteries of M109 and 1 Battery of Abbot per Bde (Until the introduction of the AS90 which replaced the Abbot and finally the M109’s at which point each Bde got 1 Rgt of AS90)
Bde Support assets:
Air support Assets (Gazelle or Lynx/Tow) would normally be retained under Bde command and operate within the Bde boundaries
Assigning SPARTY assets would normally be 1 SPARTY Bty per Rgt/Bn unless the Bde commander wanted to retain control for mass support to the ‘point’ Rgt/Bn.
Rgt/Bn Support Asssts
First thing to notice is Tank Rgt don’t contain their own Mortar Platoon, only Infantry Bns which have 8 tubes of 81mm, normally operating in 4 sections of 2 tubes although within FPRS they are 2 sections of 4 tubes, as you’ll see below it doesn’t really make much difference.
Anti-tank Platoons – mechanized or armoured infantry are Milan ground/vehicle mounted (Spartan MCT being the normal in the late 80’s), Tank Rgt were normally Striker vehicles.
Infantry Bn would normally allocate its Milan Launchers out to the companies less it’s MCT and maybe a small number of ground launchers that would be held back as Bn reserve.
Reece Platoons were similar with 8 CVRT (Combat Vehicle Recon Tracked) scorpions for Tanks and scimitar for Infantry, operating in pairs forward or on the flanks.
So under a tank Rgt Battle group they retained all their support assets and gained 4 tubes of the infantry Mortar Platoon along with the 1 or 2 Infantry companies and an number of Milan ground launchers (numbers varied depending on the task of the parent Infantry Bn). Main Anti-tank duties were expected to be picked up with either the tanks or the Tank Rgt Striker vehicles.
An Infantry Battlegroup likewise would retain all its existing support assets less those that went with the 1 or 2 companies to the Tank Rgt Battlegroup. It would not expect to receive any support assets with its Tank Sqn.
Example layout from a 2 Tank Rgt/2 Inf Bn Bde forming 4 battlegroups (2 of 2/1 and 2 of 1/2 type)
Tank Rgt BG
A Sqn
B Sqn
C Company (Infantry Bn) + 4 mortars & 5 Milan ground launchers
Standard Tank Rgt Support Elements
Inf Bn BG
A Coy
B Coy
C Sqn (tank Rgt)
Standard Inf Bn Support elements less those above
A 2/2 BG would be
A Sqn
B Sqn
C company (1st Infantry Bn)
C Company (2nd Infantry Bn)
Standard Tank Rgt support assets. although the support assets coming from the Infantry Bn would vary at this point but not unheard of for each company to have a number of its own Mortar & Milan assets
