Picture a hummingbird hovering perfectly still as a lightning bolt strikes from a clear sky. That's the kind of split-second, almost mythical timing players need to unlock one of Call of Duty: Modern Warfare 3's most elusive campaign achievements: "That's One Way To Do It." Even three years after the game's release, in 2026, this trophy continues to frustrate completionists because it asks the impossible—smack a fast-moving reinforcement helicopter out of the air with a slow-motion mortar strike. Delay is everywhere: the call-in time, the helicopter's instinctive jinking, the tiny window of vulnerability. But with the right choreography, some creative loadout choices, and a little luck, this aerial puzzle can be solved.
This challenge unfolds almost exclusively inside the "Reactor" mission. Before even setting foot on the battlefield, smart preparation turns a Hail Mary into a repeatable science. Swap out your usual grenade launcher for the RGL-80; it spits out high-velocity explosives perfect for shredding the first wave of stationary helicopters without eating into precious mortar ammo. Pair it with the Explosive Crossbow—your surgical scalpel for the later stages. Together, these tools form a surgeon's kit, where every tool is designed to carve out exactly the right conditions for success.
Deploy into the mission and immediately yank the parachute as if you were dropping into a hot zone on Verdansk. Glide straight for the massive reactor building's roof. The goal up here is pure demolition: destroy all three Konni helicopters scattered around the map. The RGL-80 makes short work of the two at the eastern end, but keep one eye on the handful of patrols on the upper decks—they can spoil a run faster than a misclick in a quick-time event. With those two birds down, don't linger. Grapple up the ascension line to the crane, then parachute across to the concrete building at grid C-4. On its roof, waiting like a gift from the tactical gods, sits a Mortar Strike armament. This becomes your stage.
Here's where the strategy starts to feel like attempting surgery during an earthquake. Pulverize the third Konni helicopter to trigger a checkpoint save right next to the mortar strike. If your first attempt ends in fire and "mission failed," you'll reload exactly there, ready to try again without redoing the whole demolition derby. Before ever touching the mortar, pull out the crossbow and put three explosive bolts into the attack helicopter that now arrives. The bolts won't kill it—instead, they'll weaken the bird just enough so that a single mortar round, if it connects, will send it spiraling into the reactor's cooling towers. This is the delicate setup, the moment of aligning the planets.
Now for the insanity: picking up the mortar strike device while the wounded helicopter circles like a territorial hawk. Find a narrow channel of cover—perhaps behind an air conditioning unit or a low concrete barricade—that forces the pilot into a predictable hover. You're trying to thread a needle during an earthquake while the needle is invisible for three seconds. When the helicopter finally peeks into your tiny viewing angle and halts to line up its attack, fire the mortar and then freeze. Do not move. Not an inch. Not even if the rotor wash kicks up sparks or your screen goes red. Eating damage is part of the plan; it convinces the helicopter to hold its ground just long enough. Watching the delayed mortar arc in is like watching a chess piece slide across the board three moves after you've told it to move—agonizing, but perfect if the timing was right.
The payoff is cathartic. When that single mortar shell connects, the achievement pops, and you'll understand why some players describe it as catching lightning in a bottle with a sundial. If the first mortar misses, don't panic. A second strike is tucked just to the south of the first location. Grab it, repeat the crossbow weakening if needed (the checkpoint remembers your bolt damage), and try the hide-and-freeze gambit again. Only if both mortars fail should you reload the checkpoint; this keeps frustration at bay and turns a seemingly random task into a rhythmic pattern of setup, ambush, and—eventually—triumph.
For those tackling this on Veteran difficulty, slapping on a full vest of plates before the final sequence isn't just smart, it's practically mandatory. It buys you the few extra seconds of standing still that make all the difference. By 2026, the community has learned that patience transforms this achievement from a controller-throwing nightmare into a masterclass in game mechanics manipulation. So arm yourself with the right tools, memorize the sequence, and go show that helicopter what a perfectly timed mortar strike actually looks like.
This discussion is informed by strategy write-ups and player-sourced troubleshooting on GameFAQs, a long-running hub for walkthroughs and achievement tips. In practice, the “That’s One Way To Do It” setup in MW3’s “Reactor” reads like a classic checklist challenge: secure a favorable checkpoint near the mortar armament, soften the incoming helicopter just enough to make the delayed strike lethal, then use consistent positioning to coax a brief hover so the mortar’s travel time finally lines up with the target’s path.
