Close Combat Lethality

Unconventional Mobility

Silent Tactical Energy Enhanced Dismount (STEED) significantly enhances human performance during dismounted operations. Maximizing small unit dominance through lethal payload transport, extended time and distance, and rapid 1:1 personnel recovery. No RF required. Patents pending.



Dismounted Payloads

Dense Urban & SubT

Medical & CASEVAC


RRTO Thunderstorm experimentation of future vehicle for multi-domain operations during first responder and military challenges encountered in dense urban environments; including buildings, streets, and subterranean rail. Zero turning radius and zero emissions enable use in confined spaces. Climbing stairs allows movement to operations occurring above and below street level, and traversing rubble piles ensures dispersed unit mobility in degraded urban terrain.

Successfully completed Combat Evaluation (CV) measuring efficacy under various operationally relevant scenarios cross-country and in dense urban and subterranean environments. Military utility assessment and comparative human performance study demonstrate significantly faster dismounted movements, improved squad situational awareness and security posture, combined with reduced fatigue and faster recovery. Remains functional when power is depleted.
— April/May 2019
Performed flawlessly while participating in the Army Expeditionary Warrior Experiments (AEWE) conducted by the Maneuver Center of Excellence Battle Lab. STEED utilized during squad, platoon, and company trials, and was highlighted as a standout technology. Carried multiple capabilities, sustainment loads, and enabled 1:1 litter casualty movement. Requires zero RF spectrum.
— February/March 2019
Selected from among multiple candidate projects as first pilot in Army Futures Command’s capabilities accelerator, the Army proponent for disruptive innovation. STEED is the closest tech to reduce Soldier load now.
— December 2018
STEED enabled one individual to continuously move multiple mass casualties during live high-intensity crisis scenarios at Operation Convergent Response, an immersive learning experience for first responders that employs emerging technology used to help save lives.
— November 2018
Load carriage using wheeled carts prescribed in FM 21-18 as a readily employable means of reducing Soldier load fatigue, extending endurance, improving effectiveness, and reducing injury. Stating ‘a Soldier’s fighting capability is related directly to their load’.

Dismounted troops have been challenged with excessive loads for centuries. And now more than ever, increased squad-level capabilities and personal protective equipment press warfighter loads over 100 lbs.

Extensive military research spanning decades, varied services, and nations consistently illustrates the deteriorating effects of load on close combat performance. Load is a pervasive problem, and substantial reductions have proven very difficult to achieve.

In April 2017, the U.S. Army’s Maneuver Center of Excellence updated Field Manual 21-18 governing dismounted movement standards and best practices. For the first time in 25 years, combat load carts were prescribed as an effective means to reduce load.

Against this backdrop, dismounted troops are being asked to do even more. Emerging concepts for movement and maneuver require dispersed small units to sustain themselves for twice as many days, and to maintain constant movement. All of this in severely degraded environments.

This is where STEED performs.

A versatile load carrier that is simple and highly-maneuverable. Zero emissions, tactically silent, no RF required. Zero turning radius submersible, even climbs stairs.

STEED enables one man to move up to 500 lbs. payload with minimal physiological effects. Food. water, ammunition, crew-served weapons, EW equipment, medium robots, far forward medical gear, CBRN countermeasures, engineering kit. Nearly anything.
