In military training, it makes sense that recruits would be trained in the use of weapons. It makes sense that they would be trained the details of whatever specialty they will be assigned. But why are they taught military drills? In fighting a war, they aren't going to be marching side by side in perfect step with each other.

The OP was talking about marching.
No, the only Question in the OP was about Drills, there was a comment made about marching.
Most likely because the Potomac Bob, and many others, Confuse Drill & Ceremony with Marching.
Drills are Battle Drills most armed forces of the world, and paramilitary organizations from police and fire departments, to marching bands, use a Ceremonial form of the Battle Drills used from the "Pike & Shot" era through Rifled Muskets; sometimes into the 1940's and beyond, but mostly ended by 1916...
Marching is Marching, and is still used by every armed force on Earth. Most often marching is used to move formations (aka groups) of soldiers (etc.) from one location to another. Such as from the barracks to the Mess Hall (now D-Fac); or to a medical facility or gymnasium for inoculations, or a briefing. Marching is also used to travel significant differences; often termed a Route March that is not done with every soldier In Step but rather at Route Step which means the soldiers maintain the same pace, and a set distance, typically 1 to 3 meters, up to possibly 5 meters, but not in synchronicity. Soldiers, in particular Infantry, are still required to be able to March (standards vary between various forces/units) from 12 miles (~19 km) in 3 hours to 20 miles (32 km) in 5 hours.
The last time that a significant force had to March a significant distance to engage in combat was the UK/British Army during Operation Corporate, the liberation of the Falkland Islands. Due to too many of the British helicopters were damaged/destroyed when Atlantic Conveyer was struck by an Exocet missile; the British forces had to "Yomp (foot march) from San Carlos Water to Port Stanley, and the Paras to Goose Green. That is the last "wartime" Operational march I can recall. Tactically, Foot Patrols in Afghanistan and Iraq, and elsewhere require using Route March techniques. Soldiers from the Republic of India, as well as Communist China train to be able to march in the rugged Himalayan Mountains, and have engaged in conflict with each other in areas with no roads, and difficult or impossible to reach by helicopter. Jungles, swamps/marshes, as well as mountains and other inhospitable terrain, that might be deemed strategically valuable; or providing access to strategic locations, may be difficult to access by vehicles or even aircraft. Urban areas are also places where travelling by foot is necessary or desirable.
Back to Battle Drills what we use for ceremonies, such as parades, were, until rather recently, used to Tactically Maneuver soldiers in Combat! In the 21st century we would most likely use the command: "Platoon! By Squad. File From The Right, Collum Right!" Moving the soldiers into a Mess Hall, or TMC (etc.). Less than a hundred years ago that was how soldiers moved from a collum of march (typically four collums wide) into a Line of Battle. Since c.1865 (or so) it would be likely to add: "At The Double" and "At Extended Interval." This would deploy an Infantry formation (typically a Company to a Regiment) in a "Line of Skirmishers" with 1 to 3 meters between soldiers. These techniques were universally employed from the 1870's through the 1950's.
Those tactics evolved into tactically moving in a "Wedge" ^ (or "Reversed V"); but still deploying On Line for maximum firepower once in contact with the enemy. Infantry Tactics in use today developed from German tactics from pre-1914, but in particular their Strum ("Storm") tactics, which were basically "Combined Arms" by which they meant not just rifles, but also machineguns, mortars, grenades, grenade launchers, and other weapons. As well as "Infiltration Tactics" meaning bypassing nodes of resistance, and using terrain and suppressing fire to move into an enemies depth. Then follow on forces would neutralize the bypassed nodes of resistance; preferably by attacking from the flanks or rear. All modern armed forces use only slightly modified tactics used by some German units as early as 1914!
A difference is that instead of an Officer or NCO yelling, "Platoon! By Squad. File From The Right, Collum Right! At Extended Interval. Form A Line Of Skirmishers! AT THE DOUBLE!"
A leader would now command: "Action Right" or give the Hand & Arm signal for that maneuver by making several rapid punching motions at shoulder level.
Similar Battle Drills (maneuvers) are conducted by a Platoon or Company of Tanks or other AFVs.
In conclusion, Drill & Ceremony is still taught in Basic Training, partially as one of the tools of installing discipline; but also, as a "building block" of moving troops in a Marching Formation, or from a marching formation to a particular location. For example: after being transported by truck to a rifle range, the soldiers unload, then are moved to the safety area behind the firing area and formed up so they may all be more easily accounted for, weapons inspected, etc. Then the personnel may be safely and orderly deployed to firing positions. Often, they will be cycled through an ammunition issue point, again using those "archaic" Drills.
So, while "Close Order Drill" is now used for ceremonial functions, or a variation is used to move soldiers in an administrative situation (from a barracks to a classroom, mess hall, etc.). Close Order Drills are also a building block for Tactical Maneuvers. Many soldiers may not be aware, nor care, about the history of these Drills. Drills are Battle Drills, even if some particular drills are no longer tactically viable. "Close Order Drill" is still the basis for Riot Control formations. Battle Drills and Marching are still necessary skills that should be learned by all members of armed forces. While members of the Air Force might only use it to get to a D-Fac, or an awards ceremony; Army and Marine Infantry use variations of those maneuvers in their current Battle Drills.
Watch some videos of a collum of Tanks and other AFVs deploy from a Road March into a line of Battle in the current war in Ukraine. Such a deployment would be recognized by a Sergeant or Colonel in the Army of the Potomac in 1863, or a Centurion in 43 A.D.
