Full description and what we offer
03ELEVEN Tactical is a veteran and law enforcement-owned training organization based in St. Louis, Missouri. The outfit was founded by Brian Rossomanno (28-year St. Louis Metro Police veteran, former Marine infantryman, 12-year SWAT member) and Craig Grob (10-year Marine Corps vet, Scout Sniper Team Leader, 7-year St. Louis Police SWAT operator). Their entire instructor cadre comes from active duty or recent service—no classroom-only guys.
The core principle: training is distilled from decades of actual operational experience, not theory. Their motto sums it up: "We don't rise to the level of our expectations, we fall to the level of our training."
