The Blurring Lines: Wheeled AFVs and the Evolution of Ground Combat

By Dr. İpek İpek

Something fundamental has shifted in how we think about armoured vehicles, though it took the grinding reality of recent conflicts to make the transformation visible. The once-clear distinctions that separated wheeled from tracked platforms—lines that shaped procurement decisions and doctrine for decades—have grown increasingly blurred. What we are witnessing is not merely technological progress, but the quiet collapse of categories that no longer reflect the demands of modern warfare.

During the Cold War, the division of labour was simple and rational: tracked vehicles fought, wheeled cars transported. The M113 and MT-LB embodied this approach—affordable, mass-produced platforms that could be endlessly adapted. Their wheeled counterparts, such as the BTR family, operated under slightly different assumptions but with the same logic of specialisation. Each type had its place in a world where armies could afford the luxury of clearly defined roles.

That luxury has since vanished. Shrinking budgets and expanding missions have pushed militaries toward platforms that promise versatility without significant compromises. The new generation of 8×8 wheeled vehicles, especially from European and Middle Eastern manufacturers, not only reflects incremental improvement but also a rethinking of what armoured cars are meant to do. Their adaptability in various combat situations is a reassuring factor.

The Boxer is the most emblematic example. ARTEC’s modular design—separating a drive module from interchangeable mission pods—suggests a future where vehicles adapt to missions rather than the other way around. At the same time, elegant in concept and often practical in practice, limitations remain. The transition from A0 to A2 standards demonstrated how evolving requirements still force chassis changes, and fixed dimensions impose constraints no engineering trick can erase.

Nevertheless, the appeal is undeniable. Smaller armies, in particular, have embraced wheeled platforms with enthusiasm, grateful for their operational mobility: no heavy equipment transporters, a reduced logistical burden, and greater ease of strategic deployment. Yet what is less apparent is how this shift reshapes tactical thought.

The Doctrine Gap

Frameworks like Leo Purdy’s “Iron Triangle”—emphasising dismount capacity for APCs and protection and firepower for IFVs—made sense when vehicles stayed in their categories. Today, those boundaries are increasingly irrelevant. The BTR-4’s use in Mariupol illustrates this: a car classified as an APC was employed with its 30mm cannon against enemy IFVs, performing admirably. Was it an APC acting as an IFV, or had the distinction ceased to matter? On the ground, doctrine gave way to necessity.

This collapse of categories affects procurement as much as combat. When manufacturers market 8x8s with 30mm cannons as IFVs, it is not mere exaggeration—it reflects demand from customers unwilling to accept rigid roles. The British Army’s ongoing struggle to replace the Warrior underscores the tension. Despite Boxer’s versatility, the army has shown little interest in adapting it into an IFV role. Tracked vehicles still offer superior tactical mobility and protection, while heavily armored wheeled platforms face penalties in terms of size, visibility, and weight.

Manufacturing Realities

For the industry, this convergence presents both opportunities and challenges. ARTEC’s interchangeable modules represent one vision of modularity. Still, Turkish firms such as Otokar and FNSS offer another: factory-produced variants of adaptable base platforms like the Arma and Pars Alpha. This approach reduces engineering complexity, shifting decisions from operators to procurement officials, while still delivering a wide range of roles from mortar carriers to air-defence variants.

The economics are compelling. True modularity is costly in R&D terms, while configurable designs offer much of the same flexibility at lower development expense. Turkey’s next-generation programme illustrates the trend: both the Pars Alpha and BMC’s Altuğ were selected, signalling that wheeled platforms are now credible alternatives to tracked systems across diverse roles.

Tactical Implications

This shift is more than a simple substitution. Wheeled AFVs not only replace tracked vehicles but also enable new approaches to ground combat. Operational mobility has become as necessary, and sometimes more critical, than tactical mobility. Yet constraints remain: soft ground still favours tracks, and heavy armour on wheels inevitably leads to oversized vehicles with demanding powertrains.

The blurred line between APC and IFV functions offers both opportunities and risks. Units equipped with heavily armed wheeled platforms may be tempted to use them aggressively, regardless of whether they are optimised for such roles. Ukraine’s success in Mariupol cannot be assumed to translate into doctrine. This cautionary note should make us all more aware of the potential risks of the shift.

Looking Forward

What we are seeing is less revolution than evolution: untidy, uneven, driven as much by budgets as by technology. The sharp Cold War-era divisions reflected a world where roles were affordable and predictable. That world is gone. Today, manufacturers that thrive are those that embrace ambiguity, offering practical and flexible solutions for missions not yet fully defined. This adaptability should instill confidence in the industry’s future.

The marketplace is increasingly dominated by wheeled vehicles designed to perform multiple tasks reasonably well, rather than one task exceptionally. Whether that is progress depends on perspective. For smaller or budget-constrained militaries, the appeal is obvious. For those preparing for high-intensity conflict against peer adversaries, the trade-offs may be more troubling.

What is clear is that the old categories—APC vs. IFV, wheeled vs. tracked, transport vs. combat—are losing relevance on the battlefield. They persist in manuals and procurement language, but their utility in real combat is increasingly questionable. Whether this evolution marks adaptation or a gamble against reality remains an open question.
