WHAT IS TIER ONE SUPPLY?

Tier One Supply is a company specialized in comprehensive solutions for LEAF, SAR, and High-Risk Operations units.

We operate globally as a hub for consultancy, distribution, and training, connecting manufacturers of advanced materials and technology with end-users operating in high-risk environments.

Our primary focus is maritime and underwater scenarios—including technical, military, law enforcement, and SAR diving—which we complement with capabilities in land and air operations, integrating UAS/drone platforms, communications, and mission support systems.

OUR MISSION

Our mission is to provide 360° solutions to special operations and rescue units by combining high-performance equipment, operational consultancy, and advanced training.

We work to maximize safety, efficiency, and interoperability in critical missions, particularly in maritime and underwater environments, while also ensuring integration with land and air capabilities (including UAS/drone systems).

We act as a bridge between industry and the end-user, ensuring that every system, configuration, and operational protocol aligns with real-world operational needs.

CONSULTANCY

Our consultancy services are aimed at front-line units: special forces, rescue teams, tactical divers, and maritime and coastal units.

We provide guidance on the selection and configuration of diving systems, EBS, communications, UAS/drone platforms, and tactical equipment, tailoring each solution to specific doctrine, procedures, and operational environments.

We support manufacturers and end-users during testing, evaluation, and deployment, including operational demonstrations, integration with existing SOPs, and assistance in defining technical requirements

SUPPLY

We manage the distribution of advanced equipment for professional and special operations, with a particular focus on maritime and underwater domains: technical and military diving systems, EBS, protective suits and gear, and mission-critical accessories.

We complement this catalog with selected solutions for land and air operations, including UAS/drone platforms, sensors, tactical lighting, and mission support systems.

Our value goes beyond logistics: we provide technical support, product training, and after-sales service that keeps equipment always “mission-ready.

TRAINING

We design and deliver training programs tailored to special units, rescue teams, and professional divers operating in high-risk environments.

Our offerings range from instruction on specific systems (rebreathers, EBS, buoyancy equipment, UAS/drone platforms) to advanced modules on procedures, operational safety, and integrated work across land, maritime, and air teams.

Our approach combines expert instructors’ experience with realistic scenarios and outcome-oriented assessments, ensuring every operator is fully prepared for real-world missions
