CHAIN, JOHN

US ARMY SPECIAL FORCES

MOS: 18D (MEDICAL)

SERVICE: 1996-2017

Hacker. Medic. Operator.

Coding since '89 — Defending since '96

I wrote my first lines of code at 10 years old. Ran a Wildcat BBS as a teenager. Attended DEF CON before most people had internet. By the time I joined the Army in 1996, I'd already worked at Westwood Studios as a playtester on Command & Conquer and built rendering farms in Las Vegas.

21 years as a Green Beret medic (18D), I merged those worlds — standing up cyber initiatives on active duty while still kicking down doors. ASM, Pascal, C in the '90s evolved into modern offensive security and cloud architecture.

Retired in 2017 to found Chain Enterprises. Now I bring three decades of hacking and two decades of special operations to protect what matters most — your infrastructure, your data, your mission.
