Difference between mechanized and Armoured Infantry

#3
Armoured infantry move forward in their vehicles with the tanks and dismount for the final assault. Mechanized Infantry use their vehicles to move around, but due to the light armour of their vehicles, advance and assault as standard infantry.


At least that is how it was explained to me.

Was this due to a change in tactics? Althought WR clearly has a more potent Fire Support capability than FV432 (30mm cannon Vs GPMG/LMG) was the structure and tactics of the force really much different?

Why the change? In other armies the terms seem to be almost interchangeable...... :?

Armoured - Warrior.
Mechanised - Saxon / 4 Tonners.

Or at least that's the simple way I look at it! 8O

Yes. It's not just the greater firepower of WR but also greater mobility and protection, compared to FV432. A lot of effort went into developing new drills and tactics for armoured infantry.

The term mechanised infantry continued to be used for FV432-equipped units, and still is for Bulldog (up-armoured upgraded 430 series).

4 tonners would be motorised by most standards though. Saxon would qualify as mechanised by early Russian Cold War standards, certainly by British WWII standards...... :?

If memory serves, and it probably doesn't, when I first joined the infantry in Germany equipped with 432s were called 'Armoured Infantry' and were used with advancing with the tanks and de-bussing when they were on top of the objective or very close to it. The mechanized infantry, which seemed to be based everywhere else, were moved around in 4 tonners and advanced on foot with the tanks in a style that seemed as if it wouldn't look out of place in WW2.

That sounds more like the airportable battalion in them days. Nearest equivalent now would be the light-role infantry battalion.

Currently I believe that there are 4 types (generally) of infantry operations

Armoured (Warrior)

Mechanised (Saxon being replaced by Bulldog)

Light ( wheeled and including arctic & Jungle)

Air assault (Including Para & Heliborne)

I am, however, very receptive of correction :D

"Armoured Infantry" is a British Term, no one else in NATO uses it.

German infantry in Marder are termed 'Mechanized Infantry' by them.

US Infantry in Bradley (extremely similar to Warrior) are known as 'Mechanized Infantry' by Uncle Sam.

Ditto the majority of NATO nations who employ infantry in tracked vehicles and who work in close proximity with tanks. In fact, most nations have what the Brits would call 'Permenant Battle Groups' - a unit with four sub-units, two of which consist of tanks, two of which consist of 'Mechanized Infantry Companies' (insert vehicle type according to nation...) - and they call them 'Battalions'. Imagine! A dedicated Battalion sized group, with 2 companies of tanks and two IFVs that lived, worked and trained together!! It would never catch on!

Do the maths.

I seem to recall when I was in Junior Leaders we did Army in the Contemporary World lessons. ('87).

IIRC "A" and "B" type infantry roles were talked about

I've not worked from Wr/432s, but as I understand it,

Mech - some protection and firepower. Transported around in vehs, dismount before contact and fight as light role inf; just with more mobility out of contact. Vehs could be wheeled or tracked.

Armd - far better protection and firepower. The idea is for the veh to go fully into the attack to debus closer and to give F/Sp. Vehicles are almost always tracked.

I'm thinking the former would be Saxon or Bulldog/432, or even arguably the new PPVs if in a COIN scenario, and the latter would be Warrior - it would need to have a turreted gun for F/Sp and not just a GPMG for self defence.

On the international stage it would be the difference between a BTR and a BMP/BMD, or a Stryker and a CV90, or a Fuchs and a Marder/Puma.

I'm sure some ninja of armoured doctrine will be along soon to correct me tho!

In the 1980s the British Army line regiments initially had three basic varieties of battalion:

Mechanised Infantry Battalions (FV-432)

Infantry Battalion Type A (Motorised - eventually upgraded to Saxon, but not called 'Mechanised' until much later)

Infantry Battalion Type B (Motorised/Light Role- these were mainly TA - had some organisational differences at various times, such as the inclusion of an Assault Pioneer Platoon, but were not upgraded with Saxon)

The fourth type - Armoured Infantry - was added with the introduction of Warrior. Prior to this, the British Army had had no 'Armoured Infantry'.

The US Army did have 'Armoured Infantry' during WW2, though this was a description of their role (supporting armour) and did not necessarily indicate that their vehicles were armoured. The Americans changed the title to 'Mechanised Infantry' after WW2.

The Germans have always used the term 'Panzer-Grenadier' to describe infantry units that support tanks. However, although all Panzer-Grenadiers in recent times have been equipped with armoured vehicles, this was not always the case - most Panzer-Grenadiers in WW2 rode trucks. The 'Panzer' bit reflects the role, not the degree of armoured protection - this is somewhat different to British Armoured Infantry.

During the Cold war (just after WW2 rather than the 80s), there was at least one "lorry mounted" infantry Bde.

I assume they were all in trucks, where as in those days many would have been on foot or reliant on RCT transport.

The WR and Bradley are referred to as (by NATO) MICV or Mechanised Infantry Combat Vehicles.

Hi Choc Frog,

As far as BAOR was concerned:

The 'lorried' infantry were the Type A & B Battalions, though the Type A became Saxon-mounted in the mid-1980s, as the Saxon became available.

2nd Infantry Division was the main infantry component of I Br Corps and BAOR. It had one regular Infantry Brigade (24th) of 2x Type A Bns and 1x Type B Bn. The other two brigades in the division were TA Infantry Brigades with up to 5x Type B Bns each. However, 24th Brigade was eventualy re-roled as Airmobile, with yet another organisation.

19th Infantry Bde was assigned to 4th Armoured Division. Again, it had 2x Type A Bns and 1x Type B Bn.

Another infantry brigade assigned to NATO was 1 Infantry Bde, which was the main British component of AMF - it had 3x Type A Bns and 1x Type B Bn, plus armour, recce, etc.

The Mechanised Infantry Battalions of BAOR (and later the Armoured Infantry Battalions) were all massed in the eight BAOR Armoured Brigades and the Berlin Brigade.

19 Inf Bde was all Saxon I seem to remember in 1982. Although we had two Land Rovers in the Int Cell; what do I know !

Armoured Infantry = Warrior
Mechanised Infantry = FV432

The rest was Saxon or 4 tonners

That was how I saw it but I may be wrong....
