Where Everything Fights Everything

In the annals of improbable confrontations, few matchups have generated quite as much academic discourse as the meeting between Bradypus variegatus and the M1 Abrams main battle tank. The Cambridge Institute for Absurd Comparisons devoted seventeen months to this study, during which time the sloth being observed moved approximately four metres.
What emerges from this exhaustive analysis is a portrait of two entities that have, through vastly different evolutionary pressures, arrived at remarkably similar conclusions about the value of deliberate movement. One conserves energy through biological adaptation; the other conserves fuel through tactical patience. Both, it must be said, are absolutely terrible at climbing trees quickly.
The sloth achieves this criterion with embarrassing ease. To match a sloth's annual energy consumption, a tank would need to operate for approximately 0.003 seconds. The Oxford Energy Institute calculates that replacing the British Army's tank fleet with an equivalent mass of sloths would reduce the defence budget's carbon footprint by 99.97%, whilst arguably providing similar territorial coverage speeds.
The tank's ability to operate across diverse environments, from arctic tundra to tropical heat, represents genuine strategic flexibility. The sloth, by contrast, would expire within hours if deployed to the Sahara. Military historians award this criterion to armoured vehicles, whilst noting that sloths have never required deployment because they've never started a war requiring one.
Pure velocity favours the tank by a factor of 266 to 1, though this advantage diminishes considerably when one accounts for maintenance downtime, refuelling requirements, and the tank's complete inability to navigate the rainforest canopy. The Edinburgh Centre for Practical Comparisons awards this criterion to the tank, whilst noting that neither contestant would win a race against a particularly arthritic tortoise with a head start.
Against conventional threats, the tank's armour proves vastly superior to the sloth's strategy of aggressive lethargy. However, the Manchester School of Evolutionary Defence notes that the sloth's approach requires no maintenance budget, no supply chain, and has never once been targeted by a Javelin missile. The criterion goes to the tank, though the sloth's 64-million-year track record suggests its methods have considerable merit.
When measured against evolutionary timescales, the tank is essentially a mayfly with armour plating. The sloth has weathered asteroid impacts, continental drift, and the invention of agriculture without significantly altering its lifestyle. The Cambridge Long-Term Survival Index awards this criterion to the sloth with what researchers describe as 'almost embarrassing certainty'.
The Winner Is
The tank prevails with a score of 58 to 42, though this victory requires considerable contextualisation. In immediate tactical terms, yes, a tank could theoretically defeat a sloth in direct confrontation, assuming the sloth remained stationary long enough to be targeted, which, to be fair, it almost certainly would.
Yet the broader analysis reveals uncomfortable truths about martial dominance. The tank represents humanity's apex of mobile warfare, a triumph of engineering that consumes resources at rates that would give economists anxiety attacks. The sloth represents evolution's verdict that doing almost nothing, very slowly, forever constitutes a perfectly viable survival strategy.
The Royal Institute for Comparative Success notes that by every metric except violence, speed, and the ability to destroy buildings, the sloth has achieved considerably more enduring success than any armoured vehicle. Its operational costs are negligible, its environmental impact minimal, and its 64-million-year service record remains unmatched by any weapons system in human history.
