The TT URO is UROVESA's Spanish 4x4 off-road truck family for military, emergency-service, municipal, industrial, and other special-purpose users. It sits above the lighter VAMTAC tactical vehicle line as a heavier modular truck platform, with defence 4WD versions documented at 14,000-16,000 kg gross vehicle weight, civil URB versions up to 18,000 kg, and Spanish Army MAT 18.16 service as a Light Gun artillery tractor.
UROVESA treats TT URO as a modular truck family. Public sources identify defence 4WD, municipal URB, and service designations such as MAT 18.16 rather than one fixed vehicle body.
| Variant | Configuration | Designation notes |
|---|---|---|
| TT URO 4WD | Defence and special-purpose off-road truck | Official product data lists a 240-326 hp engine range, manual or optional automatic gearbox, full-time 4x4 transfer case with locking differential, and 14,000-16,000 kg gross vehicle weight. Sources: UROVESA TT URO 4WD |
| URO MAT 18.16 | Spanish Army artillery tractor and support truck | Spanish Army reporting in 2019 described older URO MAT 18.16 trucks with more than 20 years of service in field artillery units, where they towed 105 mm Light Gun howitzers before replacement by VAMTAC SK95 vehicles. Sources: Spanish Army VAMTAC SK95 Tests |
| TT URO URB | Urban and municipal special-purpose truck | UROVESA presents the URB branch for municipal services in constrained urban, semi-urban, and rural environments, with diesel, CNG, and electric power options and 16,000-18,000 kg gross vehicle weight. Sources: UROVESA TT URO URB |
The MAT 18.16 service designation gives the TT URO page a documented artillery-support relationship without implying independent conflict use.

 | 105 mm towed howitzer | The Spanish Army identified the older URO MAT 18.16 as the field-artillery vehicle used to tow Light Gun howitzers, the role later targeted for replacement by the VAMTAC ST5 SK95. Sources: Spanish Army VAMTAC SK95 Tests |
TT URO and VAMTAC are separate UROVESA product families in the catalog: TT URO is the heavier off-road truck line, while VAMTAC is the lighter high-mobility tactical vehicle family.

 | 4x4 high-mobility tactical vehicle | UROVESA presents TT URO and VAMTAC as distinct vehicle families on the same product range, and Spanish Army reporting describes VAMTAC SK95 as the successor vehicle for the Light Gun tractor mission previously performed by MAT 18.16 trucks.

TT URO coverage is strongest as a relationship-only support page because public sources document the truck family, service roles, and compatible artillery mission more clearly than direct use in a named catalog conflict.
Spanish Army MAT 18.16 trucks served as Light Gun towing vehicles in field artillery units before the VAMTAC ST5 SK95 replacement program.
UROVESA lists command, surveillance, communications, tanker, rescue-crane, cargo, personnel, squad-transport, municipal, construction, forest, and rescue-service applications across the 4WD and URB branches.
The URB version is aimed at urban and municipal service work, including constrained streets and rural environments, with diesel, CNG, or electric power options.
UROVESA identifies 1981 as the foundation year for URO Vehiculos Especiales S.A., the company behind TT URO and VAMTAC vehicles.
