Revisiting the Light Strike Concept

Ali quotes

Light Strike was new wine in old bottles idea I had a while ago, a concept based on modernising Cold War-era ideas of a highly mobile anti-tank screening force.

Without falling into the trap of drawing cast iron conclusions from Ukraine, thought it might be interesting to revisit.

Russian performance in Ukraine should not be used as a cast-iron indicator of Russian performance in a future conflict. Does NATO really want to bet on Russia learning nothing and doing nothing?

Old Wine

The idea for an air-mobile light infantry force with a preponderance of ATGW, at least for the UK, has its genesis in the post-Falklands era. In 1983, 6 Infantry Brigade, part of 1 (BR) Corps, were renamed 6 Airmobile Infantry Brigade, a two Battalion brigade. Trials took place in 1982 during Exercise Lionheart.

The trials of 6 Brigade of 1st British Corps in an airmobile role have begun, and the first results in Exercise Lionheart were distinctly encouraging.[1]

The experiment used 6 Airmobile Brigade as a Corps reserve, flying small teams forward to take up defensive anti-tank positions. After some success, the role passed to 24 Airmobile Brigade, with 6 Brigade converting to armour in 1988.

In the years that followed, 24 Airmobile Brigade developed the capability.

Also in the late eighties, the NATO Northern Army Group Commander noted the potential for this as a larger operational reserve concept for the NORTHern Army Group[2] (NORTHAG). However, by the late eighties, the momentous changes in the Warsaw Pact countries and the Soviet Union began to unwind the threat, and efforts to further develop the concept slowed.

Despite this, and as part of NATO re-organisation in the early nineties, Exercise Certain Shield in 1991 tested an ad-hoc Multi-National Airborne Division (MNAD).

The fundamental requirements for the MNAD were:

To be able to deploy up to 120km regardless of ground conditions and obstacles

Sustain itself for 48 hours and redeploy 48 hours after withdrawal

Block, contain or delay an enemy penetration

Secure a line of departure for friendly formations

Provide flank protection

Or in other words…

It is important to note that it was designed to be used repeatedly, not just a once shot.

In response to the intelligence of an impending Warsaw Pact invasion, reconnaissance teams would fly forward to determine the optimum positions to establish tank-killing zones using rapidly deployed Milan ATGW teams.

Once the positions had been determined, the Support Helicopters would deploy teams where they would hand dig field defences and lay in wait.

TOW missile-armed Lynx helicopters would also integrate and overlap with these positions.

Artillery was generally limited; the force was armed mostly with direct line of sight ATGW.

MNAD would go on to become MND(C)[3], with 24 Airmobile Brigade joined by the Belgian Para-Commando Brigade, Netherlands 11 Airmobile Brigade, and German 31 Luftlandebrigade.

In September 1999, 24 Airmobile, 5 Airborne brigades, and 9 Regiment AAC, amalgamated to form a combined air assault brigade, what is now 16 Air Assault Brigade Combat Team.

Observations

Skip forward a few decades, does this concept still hold true?

A few observations.

How Far to the Rear is Rear?

Improved enemy long-range detection capabilities mean that reserves are more vulnerable the closer they are held to employment areas. Long-range missiles also mean that basing areas can be held at risk by short-range ballistic missiles and long-range rocket artillery.

The logical endpoint of this is that the 500km (ish) range[4] of an Iskander SRBM is the defining deployment range requirement of any future Light Strike force, accepting that Iskanders are unlikely to be launched from inside NATO territory.

Either that or use dispersal and concealment closer in to avoid being sucker-punched.

How they cover that 500km objective is the next observation.

S-400 Force Fields and Other Circles on a Map

The MNAD force used a combination of UK and German support helicopters to cover their 120km objective range.

One of the most significant recent trends in the employment of support helicopters in air manoeuvre is the increasing proliferation and capability of air defence systems, again, something clearly visible in Ukraine.

Although we are all used to seeing missile engagement enveloped described as circles on a map, they are not force fields. Even a modern integrated air defence system can be defeated, although this would require significant resources that are likely to be heavily tasked elsewhere[5]

It seems unlikely NATO forces would fly support helicopters across the Suwalki gap in response to an incursion into the Baltic states, for example. This leads to a decision point, Light Strike either accepts the risk of air operations in the potential engagement envelope of enemy air defences, requires significant SEAD/DEAD resources, or it stands off and deploys the last leg on the ground.

This latter option is preferable.

It will have to cover the last 100-150km to its objective on the ground in most scenarios.

Operating on foot is excluded, some form of vehicle will be required. Light Strike would therefore likely operate as a vehicle-borne, airmobile force.

The air mobility leg could be either a Support Helicopter or fixed-wing tactical/strategic transport aircraft. The former would be at the outer extremes of typical operating range but the flexibility of helicopters to fly low and land pretty much anywhere is obvious.

Fixed-wing aircraft can obviously travel much faster, carry greater payloads, and fly further, but they require fixed infrastructure. Landing on roads and tactical airstrips would provide some risk mitigation for fixed-wing aircraft

Being able to use both, affords greater flexibility and employment options.

The World Has Moved on Since Milan

ATGWs are every bit as lethal now as they were in the days of Milan and TOW, arguably even more so. Missiles in service such as Javelin provide a 2km plus fire and forget anti-tank capability with very high accuracy and lethality.

But even Javelin is relatively long in the tooth[6].

Non-Line of Sight weapons like loitering munitions, guided mortar bombs, and even older missiles like Brimstone allow the firing/launch point to be separated from the operator/observer. This is important as vehicle APS develop, they will be integrated with fire control ‘slew to cue’ systems, networked with counter ATGW missiles and other means of negating the threat of small ATGW teams.

We cannot stand still, and do not want to be in close range ‘fair fight’.

Light Strike should use conventional ATGW, of course, but it should also exploit modern systems, especially those that provide stand-off attack options.

Trucks Are Just as Important as Tanks

In the MNAD concept, the assumption was the target set would be lead elements of an armoured column, but in more up to date scenarios, we might see airborne forces or various recce elements, and as seen in Ukraine, high-value targets like air defence, artillery or logistics can be acutely vulnerable to small mobile teams.

Direct fire unguided weapons will have equal utility to guided weapons against these less well-armed targets where the risk environment allows them to be used.

Rising Tides

If Russian forces are going to take on Poland or the Baltic States, there will likely be rising tensions and an abundance of intelligence about where they will be.

It seems unlikely NATO will be taken completely by surprise so pre-positioning might be an alternative to rapid mobility.

Maybe a counterpoint to this proposal?

Area of Influence

Small UAS and other advanced sensors mean any given unit can cover a much greater area than before, where coverage was generally limited by direct observation.

Tethered or untethered UAS, or simply using ISTAR provided by satellites or aircraft, technology will allow Light Strike to see all, and know all. (Terms and Conditions May Apply)

Counter Detection

This also applies to enemy forces, so counter UAS and observation will need to be focus areas, cam nets and random foliage are just not enough.

Using NLOS weapons, off route mines and other systems will also continue to counter-detection and survivability.

The first layer of the survival onion is ‘don’t be there after all.

Human Factors and Logistics Support

48-hour mission duration was based on a number of factors, not least the ability to carry enough munitions. With a greater percentage of hitting the target, a wider range of weapons and potential for uncrewed UAS sustainment, we might be able to extend. Human factors remain a constant, and important consideration if operating beyond a few days. During Certain Shield, the airborne elements were supported by a road party.

Combat Engineering

Concealment and protection of observation and firing points will require more than just some cam nets and tree branches, unlike the MNAD approach, there should be some combat engineering support for field defence construction.

New Bottles

The last time I looked at this[7], the working assumption was it would be a development of 16AAB but I think this was flawed, and it would be more applicable to utilise Light Role Infantry and Light Role Cavalry as the building blocks for a Light Strike Brigade.

We could also build Light Strike using existing equipment as a first increment; Land Rovers and Javelin, 81mm mortars, quad bikes, Exactor and a radio link to a GMLRS.

This would allow experimentation to take place, developing concepts of employment and requirements for follow on developments.

To fully realise the potential for Light Strike there would need to be greater investment in vehicles, support equipment and weapons. Even these would be modest, mostly, or completely off the shelf.

We could go ultralight, quad bikes, ATV and agricultural vehicles painted green.

Or pickup trucks and other similar military vehicles.

Or even light protected or bespoke airmobile combat vehicles, although this would push the transport requirement up significantly.

As with all these options, we trade one feature over the other.

For weapons, take your pick from the cast of thousands, mortars, missiles, loitering munitions, there is no shortage of any of them.

 

Summary

I certainly don’t want this to be seen as a ‘Ukraine tells us x’ type of post because there will be a mountain of those and in my view, far too early to tell. We need to complete some careful analysis of the facts, away from the harsh glare of social media hot takes.

That said, the concept of a highly (air/land) mobile and heavily armed response and ambush force had utility in the Cold War, and there is no reason to suggest it doesn’t have the same utility if it is seen as one part of a combined arms approach to the collective territorial defence of NATO countries.

It could also be delivered relatively cheaply and quickly, at any scale, and with any NATO member nation.

Access to Support Helicopters is the main limiting factor, but even without this, the European road network can still afford plenty of high-speed deployment options.

Technology now enables floating like a butterfly and stinging like a bee to be much more bee-like (sensors and NLOS weapons), but the other folks also get a vote and potentially might have the same things.

Light Strike is not about any one individual piece of equipment, it is about balancing risk.

We managed it in the Cold War, can we do it now?

Have a nice SPIKE NLOS video to be going on with, imagine half a dozen of these vehicles mooching about near that infamous convoy in Ukraine…

P.S.

I will probably do a more detailed follow up as some point, looking at the equipment options in more detail, component units and to try and square the ‘is it infantry or is it cavalry’ question!.
