- The Mercenary Soul: Even during his sanctioned leave, Krauser couldn't stand the silence of peace. He took private mercenary contracts in the world’s "gray zones," believing that a soldier who isn't fighting is a soldier who is rotting.
- The Instructor: When the U.S. government formed its clandestine anti-B.O.W. unit following the 1998 Raccoon City incident, Krauser was the natural choice for Major. He was the primary CQC (Close-Quarters Combat) instructor, known for a brutal, "survive-at-all-costs" training regimen.
- The Interest in Leon: Krauser watched Leon S. Kennedy—the "Rookie Cop" turned "Secret Agent"—with a mix of professional respect and quiet envy. He saw in Leon a man who had faced the abyss and didn't blink, and he wanted to see if that resolve was real or just luck.
Jack Krauser was never meant for a civilian life of white picket fences. He was a career soldier within USSOCOM. The man who viewed the world through a telescopic sight.
| Year | Phase | Detail | | --- | --- | --- | | 1999–2001 | The Integration | Krauser oversees the training of the newly formed "Anti-B.O.W." division. He pushes Leon through grueling survival courses in various climates. | | Early 2002 | The Intelligence | Reports surface of a former Umbrella researcher, Javier Hidalgo, making contact with black-market viral brokers in South America. | | July 2002 | Deployment | Operation Javier is greenlit. Krauser is chosen as the mission lead due to his jungle warfare expertise, with Leon assigned as his partner. |
The objective was clear: Infiltrate the South American jungle, locate the guide in the village of Mixcoatl, and track down Javier Hidalgo before he could release a new strain of the T-Virus or the T-Veronica virus into the ecosystem. The jungle was a wall of green heat. The humidity was , making every breath feel like inhaling hot soup. To most, the jungle was a nightmare of insects and rot; to Krauser, it was home. Leon was walking a few paces ahead, his eyes glued to a grainy, sweat-stained photograph of Javier Hidalgo. He was deep in thought, likely calculating the geopolitical ramifications of a drug lord with bio-organic weapons. He was so focused on the target that he almost missed the immediate threat. A Bothrops atrox—a Common Lancehead snake—coiled silently on a low-hanging branch. It was perfectly camouflaged, its head pulling back to strike at Leon’s exposed neck. Before the snake could lunge, a silver flash cut through the humid air. With surgical precision, a heavy combat knife pinned the snake’s head to the trunk of the tree. The body of the reptile thrashed for a second before going limp. Leon spun around, hand on his holster, only to see Krauser casually stepping forward to retrieve his blade.
"You're getting distracted, Leon," Krauser said, his voice a low, disciplined rasp. He pulled the knife from the wood, wiped the blood on his tactical pants, and took a measured sip from his canteen. He looked at the dead snake, then back at Leon with a predatory glint in his eye. "So, you think B.O.W.s actually exist? Oh wait... you said you faced them before, huh? The big, scary monsters of Raccoon City."
Krauser tossed the canteen to Leon, a gesture that was half-camaraderie and half-test. He didn't wait for a response before pulling a pair of high-powered binoculars from his chest rig and scanning the dense foliage ahead.
"Our guide is in a village up ahead," Krauser noted, his tone shifting back to pure mission-focus. "He'll take us to Amparo. That's where Javier is digging his heels in. Stay sharp, kid. In this place, the things that aren't mutated are still trying to kill you. Don't let the 'monsters' make you forget about the basics."
Krauser signaled "move out" with a sharp hand gesture. He was the Major, the veteran, and the predator. In his mind, Operation Javier wasn't just a mission—it was the ultimate proving ground to see who was truly fit to survive in a world where the lines between man and weapon were starting to blur.
