Military tactics
A Roman legionnaire in 1st century Rome wielded a gladius sword while an artillery piece fired stone balls over city walls. These two actions represent the kinetic or firepower function of tactics, one of four core components that define how fighting forces operate on a battlefield. The other three functions are mobility, protection, and shock action. Kinetic effects were delivered by clubs, spears, javelins, and bows until artillery arrived with the Romans. Until the mid-19th century, infantry missile firepower rarely decided battles alone. Artillery often provided the significant kinetic effects needed to win engagements. Disciplined volley fire improved hitting power for infantry at close range. This compensated for early muskets which had limited range and poor accuracy. The Crimean War and American Civil War saw rifled muskets used with flatter trajectories. Higher casualties resulted from these technological advances. Machine guns added significantly to infantry firepower at the turn of the 20th century. Modern armies rely on tanks, self-propelled artillery, guided weapons, and aircraft for their firepower.
The Battle of Agincourt in 1415 featured English longbowmen drenching French knights with arrows. Those arrows caused horses to panic and disrupted cavalry charges. Massed arquebusiers at the Battle of Nagashino in 1575 demonstrated gunpowder's impact on European warfare. Japanese warfare in the second half of the 13th century brought infantry firepower to the fore through massed volley fire by archers. The Oirat Mongol army at the Battle of Tumu in 1449 showed that cavalry could still defeat large infantry forces. Gunpowder created a relentless shift toward infantry firepower becoming decisive during late Medieval and Early Modern periods. The introduction of the rifled musket meant flatter trajectories and improved accuracy at greater ranges. Flatter trajectories allowed soldiers to hit targets more precisely over longer distances. High casualties became common as technology advanced. Defensive firepower increased so much that infantry attacks without artillery support grew increasingly difficult. Firepower also became crucial to fixing an enemy in place before a decisive strike could be launched. Tanks and other armoured vehicles rose significantly in the century following World War II. Self-propelled artillery and guided weapons now provide the firepower of modern armies.
Most armies could not travel more than 20 miles per day unless they traveled on rivers. This restriction held true for most of human history when mobility depended on foot speed. Supplies were carried by beasts of burden but did not increase overall movement capacity. Only small elements like cavalry or specially trained light troops could exceed this limit. Tactical mobility remained restricted until the latter years of World War I. The advent of the tank improved mobility sufficiently to allow decisive tactical manoeuvre. Full tactical mobility was not achieved until World War II when armoured and motorised formations succeeded. Large elements of World War II armies still relied on horse-drawn transport which limited movement within the force. Field obstacles created by military engineers often restrict tactical mobility today. Rivers, swamps, passes, and choke points have always influenced how units maneuver across terrain. Heights and natural cover can all be used in multiple ways to gain advantage. Before the nineteenth century many tactics were confined to open terrain combat maneuvers. Specialized tactics exist now for securing rooms inside buildings or navigating complex urban environments.
Personal armour has been worn since the classical period to provide individual protection measures. Barding protected mounts alongside soldiers wearing helmets and breastplates. Weight and bulk limited how much armour a person could carry effectively. Human and animal endurance suffered under heavy loads during long campaigns. By the 18th and 19th centuries personal armour had been largely discarded from battlefields. Helmets returned during World War I in response to artillery firepower threats. Armoured fighting vehicles proliferated during World War II after that conflict ended. Body armour returned for infantry particularly in Western armies following World War II. Fortifications have been used since ancient times to provide collective protection for groups. Modern examples include entrenchments roadblocks barbed wire and minefields. Military engineers create these fortifications just as they build field obstacles. The limitations of armour always affected mobility and endurance negatively. Heavy cavalry charges required expensive equipment which limited numbers available on any given battlefield. Swiss infantry armed with halberds rebalanced scales against armoured opponents at Morgarten in 1315. English longbowmen also helped counter heavy cavalry forces during Crécy in 1346.
J. F. C. Fuller proposed three tactical cycles covering the Christian era between 650 and 1850. A shock cycle ran from 650 to 1450 followed by a shock and projectile cycle until 1850. From 1850 onward a projectile cycle dominated Western and North American warfare. Tom Wintringham proposed six chronological periods alternating dominance between unarmoured and armoured forces during World War II. The first unarmoured period lasted until the Battle of Plataea in 479 BC when neither infantry nor cavalry had high kinetic power. Chariots provided some shock action while Egyptian Persian and Greek armies became better organized. The first armoured period ended at the Battle of Adrianople in 378 AD where Roman legions introduced siege artillery. Light cavalry defeated infantry through mobility until checked by armoured cavalry in the second unarmoured period ending at Pavia in 774. Heavy cavalry facilitated by stirrups and armour dominated until Swiss halberdiers countered them at Morgarten in 1315. Infantry with steadily increasing firepower became predominant during the third unarmoured period ending at Cambrai in 1917. Armoured combined arms countered by military aircraft and infantry anti-armour weapons define the current third armoured period.
German commanders in World War II understood combined arms principles from the outset of their campaigns. British commanders were late to realize these same key principles required for maximum potential achievement. Successful tactics require fighting arms to train alongside each other regularly. All elements need the same level of mobility sufficient firepower and protection simultaneously. Military aviation integrates into combined arms teams as one critical component among many others. One method of measuring tactical effectiveness is how well all arms including airpower are integrated on the battlefield. Costly and painful lessons have dogged the history of developing combined arms tactics throughout time. The synchronisation of various fighting arms achieves the tactical mission when executed properly. Air power brings significant changes to military tactics beginning in latter stages of World War I. Close air support greatly enhanced ground force effects using aerial firepower and improved reconnaissance capabilities. Interdiction of hostile air power also became possible through coordinated efforts between different branches.
Rotary-wing aircraft had a significant impact on firepower and mobility after World War II ended. Aircraft operating at low or medium altitudes remain vulnerable to ground-based air defence systems. Parachute and glider operations provided significant mobility to ground forces but reduced tactical utility once troops landed. Operation Market Garden in September 1944 demonstrated limitations of vertical envelopment strategies despite heavy losses. Vietnam War experiences showed similar constraints even with helicopter gunships providing additional firepower quickly. Aeromedical evacuation allowed rapid removal of casualties from dangerous zones during conflicts. Supplying ground forces by air was achieved successfully by the British during the Burma Campaign. German attempts to supply forces by air failed completely at the Battle of Stalingrad. Reduced mobility protection and firepower of troops delivered by air limited tactical utility significantly. These challenges persist today as armies continue integrating aviation into their operational doctrines. Aircraft provide close support interdiction and rapid troop deployment capabilities that transform modern warfare dynamics.
