So far in the conflict in Ukraine, the Ukrainian armed forces have conducted a stout and stirring defense, inflicting heavy casualties on Russian units and contesting every foot of ground.  Against long odds, Ukraine managed to defend the capital, Kyiv, as well as its second largest city, Kharkiv, forcing Russia to abandon its goal of a quick takeover of the national territory. Staving off defeat is not, however, the same thing as victory.[1]  Russian forces today control about 20% of Ukrainian territory, including large tracts in the east and south.  What can Ukraine do to “win”?

A first step must be to address the disparity in airpower.  Success in modern, high-intensity warfare is almost impossible without at least parity in the air, and Ukraine began the contest woefully behind the curve, with perhaps flyable 100 jets compared to Russia’s more than 1,500.  Where Russia has been able to generate 100-200 sorties per day, the much smaller Ukrainian air force can manage perhaps 10-20.  Accordingly, Ukraine has been generally unable to provide air support to its ground forces for fear of losing its small inventory of high-performance aircraft (mostly MIG-29 and SU-27 fighters and Su-24 and SU-25 ground attack aircraft). Instead, its approach has been to carefully husband its assets to maintain a “force-in-being,” to be used only selectively.

On the other hand, Ukraine has been outstandingly successful in denying Russia air supremacy with extremely effective air defense and a strategy of “air denial.” Though lacking the most advanced air defense systems, such as the US Patriot or the Russian S-400, its use of older S-300 (high altitude), SA-11 (medium altitude) and SA-8 (short range) systems has been lethal to Russian airpower.  (The US has also provided small numbers of its NASAM short to medium-range air defense system, while Germany has promised to send decommissioned Gepard air defense vehicles, though ammunition shortages have delayed actual use)[2]  Employed in concert with large numbers of US-supplied Stinger shoulder-fired missiles and using “shoot and scoot” tactics for survivability, Ukrainian air defense has downed dozens of Russian fixed and rotary-wing aircraft and largely sidelined Russian airpower. An adequate supply of air defense missiles for Ukrainian systems is essential here, and they must come from outside sources in quantity for  Ukraine  to prevail.

Ukraine has also used drones with devastating effect.  The principal military platforms have been the Turkish “Bayraktar” TB2, which can deliver laser-guided bombs, and the US-supplied “Phoenix Ghost” drone, as well as the “Switchblade,” a “kamikaze” drone with onboard explosives that can be flown into the target.  These are supplemented with thousands of cheaper commercial drones used for artillery spotting and intelligence collection. Russian forces have adapted and the loss rate of Ukrainian drones is high, but low cost and ready availability mean that drones will continue to play an important role.  When linked to nearby artillery units, drones enable quick target acquisition and precise fires, making the most of Ukraine’s limited artillery resources.

Ukrainian innovation and tactical agility have blunted much of Russia’s dominance in the air, but the ability to generate offensive airpower in the form of close air support and air interdiction will go far towards helping Ukraine prevail.  Earlier in the conflict, Poland and other former-Warsaw Pact nations suggested a transfer of Soviet-era jets to Ukraine, an offer blocked by US officials.[3]  If NATO is determined not to provide air cover, it is imperative that this block be removed and that partners be permitted to support the Ukrainian air force with platforms it can employ quickly to support air operations.  Backfilling these transfers with US 4th generation aircraft like the F-16 would also hasten the transition from Soviet-era jets to more interoperable western aircraft in these countries.  Even 50 additional jets, with associated munitions and spare parts, could make a major difference.[4] Without a boost in air support, a Ukrainian victory may still be possible if the strategy of air denial holds up, but it will come at higher costs to the ground forces.

Just as important is artillery, which comes in three forms – tubed, rocket and missile.  Ukraine began the war with substantial but outdated tubed artillery from the Soviet era, complicated by a dearth of ammunition.[5]  With some 2000 artillery pieces to Ukraine’s 500, Russian artillery is far more numerous, modern and powerful, with a daily consumption of artillery rounds some 10 times greater than Ukraine’s.[6] As with air defense, Ukraine has used its limited artillery intelligently, quickly relocating after fire missions to avoid counter-battery fire and relying on drones for precision targeting.  The addition of towed 155mm howitzers from the US and smaller numbers of 155mm self-propelled  systems from Germany, France and other countries has strengthened Ukraine’s tubed artillery holdings considerably, but Russia’s advantage is still strong.[7] 

Here, the US can help with M109A6 155mm self-propelled howitzers, recently replaced by the newer M109A7 model and now in storage in quantity.[8]  The M109A6 is an armored, tracked vehicle, more survivable against counter-battery fire, quicker to displace and with smaller crews.  It is accurate, lethal and rugged – well suited to Ukraine’s terrain and operational environment.  Approximately 320 of these systems would give Ukraine 4 additional artillery brigades (one for each of its 4 regional headquarters), plus an additional battalion in general support for each of Ukraine’s 12 or so division – equivalents, leaving some 10% for training and spares.

The real artillery game changer is the multiple launch rocket system, in both the wheeled (M142 HIMARS) and tracked (M270 MLRS) variants.  Both are long ranged, precise, mobile and very destructive. Small numbers have been provided to date and they have rendered excellent service.[9]  While Ukraine does field older rocket artillery systems like the  BM-21 Grad and BM-30 Smerch, HIMARS and MLRS are far superior in range and precision.  As a matter of policy, the Biden administration has withheld longer ranged ATACMS ammunition that can strike targets up to 300 miles away.[10]  To level the playing field and transition to the offense with some hope of success, Ukraine probably needs some 50 or so HIMARS or MLRS systems, and it needs the ATACMS round.[11]  These capabilities will enable Ukrainian forces to strike high value, deep targets like command posts, airfields, logistics hubs, air defense complexes, and ballistic missile launchers.  Given the mismatch in airpower, long range rocket artillery has the potential to turn the tide and put Ukraine on a path towards ultimate success. Without it, victory will be elusive.

Stronger airpower and more modern rocket artillery will greatly improve the odds, but Ukraine’s tank forces must also be strengthened.  When the war began Ukraine’s standard tank was the T-64B, an older Soviet-era design, underpowered and lacking the most modern explosive reactive armor, thermal sights and modern ammunition.[12] While Ukraine has inflicted heavy losses on Russian armor (often using hand-held antitank weapons), its own tank force has been depleted and offensive breakthroughs with tank-heavy forces have not been possible. Poland has committed to providing 240 PT-91 main battle tanks, along with small numbers of Czech T-72s.[13] To equip the Ukrainian army for offensive operations in 2023, the US should consider providing a similar number of M1A1 tanks from its large reserve stocks.  Though not the very latest model, the M1A1 is more than a match for most Russian tanks and available in large numbers.[14]

More modern weapon systems for Ukraine are badly needed, but reorganizing Ukrainian ground forces is just as important.  Ukraine began the war with some 38 maneuver (infantry and tank) brigades and 9 artillery brigades, organized on the Russian model.[15]  Unlike western armies, Ukraine does not use the division and corps structures common to NATO, relying instead on regional commands.[16]  These lack true battle staffs that can provide enablers, resource lower level commands and integrate airspace, deep fires, logistics, intelligence and operational level command and control.  This organization suffers from span-of-control problems and prevents Ukraine from conducting large-scale operational maneuver, especially for offensive operations.  A better approach is to convert the operational commands into true corps headquarters with trained battlestaffs, and to introduce the division as an intermediate echelon of command.  Both should include “enablers” or support formations (artillery, air defense, aviation, engineer, signal, logistics, intelligence, medical, and reconnaissance units) that are crucial to success in combined arms warfare.[17]  Standing up these structures in wartime will be challenging and will take time, but could be possible by the latter part of 2023 with the right support.

This move would result in the creation of 4 regionally-oriented corps, each with anywhere from 2-3 division-equivalents (including territorial defense forces) based on the terrain and threat.  To transition to the offense and counter-attack, Ukraine also requires a 5th corps composed of at least three tank and mechanized divisions – an “armored fist” led by its most accomplished and successful commanders to conduct decisive operations to drive the Russian army from Ukrainian territory.  To coordinate these corps, Ukraine should establish a field army headquarters, to be led by the Commander, Ukrainian Ground Forces.  Many of the building blocks of these formations already exist in current force structure and standing headquarters, which need only to be converted or augmented for battlefield use.

All of this requires institutional support and infrastructure to recruit, train, equip, field and sustain forces in the field as well as defense industry to manufacture, repair and replace combat systems and to produce the ammunition, spare parts and other classes of supply that are essential.  Foreign assistance has been critical in this regard, but it has come incrementally and on an ad hoc basis, challenging Ukraine to integrate many different types of combat systems, on the fly, in combat.  To assist Ukraine, NATO should provide a “NATO Training Mission-Ukraine,” based in Poland, on a scale similar to the robust training support organizations seen in Iraq and Afghanistan.[18] Led by a US 3 star, with senior-level representation and staffing from the UK, France, Poland and Germany, NTM-U can provide the expertise, technical assistance and “connective tissue” that is badly needed as Ukraine fights for its national existence.[19]

Why should the US and its European allies and partners risk a confrontation with a nuclear-armed Russia in this way?  The clear answer is that a negotiated “peace” in Ukraine will mean nothing of the sort.  Any settlement that leaves Russia in control of occupied territory in exchange for a cessation of hostilities will reward Russian aggression and encourage more.[20] Western leaders can be sure that success in Ukraine, even at high cost, will put NATO Allies like the Baltic States squarely in Putin’s crosshairs.  If anything, US and European reluctance to take the steps outlined above can only reassure Putin that the West fears confrontation and will take pains to avoid it. This is not a recipe for deterring future aggression.

Nor should the West fear Russian rhetoric about the use of nuclear weapons.  Distilled to its  essence, this amounts to the threat of a nuclear exchange if Russia is not allowed to invade and occupy its neighbors. The nuclear deterrence regime that has been in place since the 1950s is surely strong enough to deter such wild adventurism. Here, constant statements from western leaders that “we cannot risk WWIII” only encourage Putin that reckless threats to use nuclear weapons are working.

The outcome of the conflict in Ukraine will have other consequences beyond Europe.  China is watching carefully and will weigh the West’s commitment to its friends and partners carefully as it considers the military conquest of Taiwan – especially after the US and NATO’s precipitate and chaotic withdrawal from Afghanistan. So will Iran and North Korea.  For the most part, Russian aggression in Georgia, Crimea, the Donbas and more broadly in Ukraine has been met with sanctions, rhetoric and a pronounced unwillingness to risk confrontation –  not confidence and firm resolve. We should not fool ourselves here.  Much is at stake.

To enable Ukraine to succeed and win, the US and Europe do not need to introduce ground troops.  Magnificent Ukrainian resistance has badly hurt the Russian military, which is almost totally committed in Ukraine.  An opportunity exists to end further Russian aggression in the European security space for a generation, and perhaps forever.  But victory depends on western and international support that goes well beyond the current level.  We cannot ignore that Ukraine, too, has suffered painful losses in troops and materiel. Ukraine has been consistent and clear about its needs.  Peace in Europe, and perhaps the world, depends on meeting them.
