The campaign to reclaim territories from the clutches of chaos brought the Blackwatch and United States forces to their first major target beyond Hong Kong: Shenzhen, China. This sprawling city, once a bustling hub of innovation and commerce, had fallen into despair, its streets overrun by the undead. To initiate their operation, the forces employed a barrage of firepower, with HIMARS (High Mobility Artillery Rocket Systems) and artillery howitzers leading the charge. Their objective was clear: to cleanse the streets of Shenzhen from the zombie menace that plagued them.

As the first light of dawn broke over the city, the artillery units took their positions, their barrels aimed with precision at the densest concentrations of the undead. A thunderous roar followed as the HIMARS and howitzers unleashed their deadly payload, sending a series of explosive projectiles arcing across the sky. The salvo descended upon Shenzhen, igniting a series of powerful explosions that rocked the city’s foundations.

The impact was devastating. Buildings that had stood as silent witnesses to the apocalypse now bore the scars of this new onslaught. The explosions tore through the undead ranks, sending limbs and debris flying. For a moment, the city was alight with a deadly fireworks display.

In the wake of the artillery’s fury, infantry and armored units began their advance. Armored vehicles, including Abrams tanks and Bradley fighting vehicles, rolled through the streets, their turrets swiveling to engage any threats. Behind them, squads of Blackwatch and United States soldiers moved in formation, their rifles at the ready. They were the cleanup crew, tasked with eliminating any zombies that had survived the initial bombardment.

The urban environment of Shenzhen presented a unique challenge. Every street and alley could hide potential threats, and the dense urban sprawl made progress slow and perilous. But they were helped by air support from above. AC-130, A-10 Warthog, Apache helicopters, and drones provided crucial support from the skies. The AC-130 gunships, with their devastating firepower, circled overhead, raining down bullets and shells on identified zombie clusters. A-10 Warthogs swooped in with precision, their GAU-8 Avenger rotary cannons shredding through the undead with ease. Apache helicopters provided close air support to the ground troops, targeting any significant undead threats that could potentially halt the advance.

Drones, both for surveillance and combat, offered a significant advantage, giving the commanders a bird’s eye view of the battlefield. They identified key zombie congregations and relayed real-time data back to the command center, ensuring that artillery strikes were both precise and effective. This aerial reconnaissance allowed the ground forces to navigate through the city more safely, avoiding larger hordes and focusing on clearing strategic areas critical for the city’s reclamation.

As they were moving into the deeper part of Shenzhen, they encountered something.

"That’s a Goliath," Richard said, looking at the screen. Those humongous monsters with shields and an arm blade that is as tall as a building.

Richard, understanding the challenge ahead, immediately coordinated a response strategy. "Focus all available firepower on that Goliath," he ordered.

Abrams tanks adjusted their aim, targeting the giant with armor-piercing rounds, while Apache helicopters maneuvered for a direct assault, their Hellfire missiles locked onto the monstrous adversary.

The battle that ensued was intense. The Goliath charged, its shield scraping the paved streets of Shenzhen, causing debris to scatter as it moved toward the Blackwatch and United States forces with terrifying speed.

Helicopters and the AC-130 gunship worked in tandem, focusing their firepower on the Goliath’s more vulnerable spots. The Apache helicopters darted around the Goliath, avoiding its attempts to swat them from the sky. They fired Hellfire missiles at the joints of its arm and the areas not covered by its shield, aiming to cripple its mobility and offensive capabilities.

The AC-130, circling above, had a broader view of the battlefield. Its crew targeted the Goliath with a combination of 105mm cannon fire and precision-guided munitions, exploiting every opening provided by the Apache helicopters’ attacks. The relentless barrage from the air was complemented by the ground forces’ heavy artillery, which pounded the Goliath from a distance, creating a continuous stream of explosions around it.

Despite the Goliath’s formidable strength and armor, the combined firepower began to take its toll. Sparks and debris flew as its armor was pierced by the concentrated attacks. The beast roared in defiance, trying to push forward, but the damage to its limbs slowed its advance significantly.

Infantry units, taking advantage of the Goliath’s weakened state, moved in closer, using rocket-propelled grenades and anti-tank weapons to target any exposed or damaged areas.

As the Goliath finally fell, its massive body crashing to the ground with a thunderous impact, a brief silence fell over the battlefield. The soldiers, panting and scanning the surroundings for more threats, and there was. Alpha Hunters and Juggernauts.

They rushed towards their position, easily preying on the infantries of the Blackwatch and the United States forces. Their small arms weren’t effective on the tough hide of the monsters and they were quickly overwhelmed by the sheer force and ferocity of the attackers. Juggernauts, with their immense size and strength, hurled soldiers into the air with terrifying ease, their bodies landing with sickening thuds. Alpha Hunters punched through the ranks of soldiers, their powerful blows sending bodies flying into walls with such force that they left indents and cracks upon impact.

The sudden appearance of these formidable opponents caused momentary chaos among the Blackwatch and United States forces. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

"Send in the heavy cavalry," Richard directed. Immediately after his command, tanks rolled in, forming a defensive line between the remaining infantry and the advancing Juggernauts and Alpha Hunters. Their main guns thundered, sending powerful shells that exploded upon impact, causing significant damage to the Juggernauts.

Meanwhile, Bradley Fighting Vehicles, supporting the tanks, opened fire with their 25mm chain guns, targeting the quicker and more agile Alpha Hunters. The rapid-fire capability of the Bradleys proved effective in slowing down the Hunters, piercing their hides with a barrage of armor-piercing rounds.

The air support, never far behind, swooped in once again. This time, the Apache helicopters focused on the Juggernauts, launching Hellfire missiles at any of the behemoths that got too close to the Blackwatch and United States forces’ defensive line.

The intense battle raged on, with the Blackwatch and United States forces managing to hold their ground thanks to the timely arrival of the "heavy cavalry." The combined efforts of ground and air forces began to turn the tide, with the number of Juggernauts and Alpha Hunters dwindling under the sustained assault.

One hour later, mutated zombies were no longer seen in Shenzhen, they were all eliminated.

"Shenzhen captured!" Richard announced.
