The 307th Marine Regiment is the specialised unit of the Naval Forces, designed to execute land, riverine and amphibious operations (as Amphibious Landing Force), in support of the coastal defense and security with critical infrastructure elements of this area.

The main tasks of the 307th Naval Infantry Regiment include the following:
(a) coastal reconnaissance and surveillance;
(b) protection of critical infrastructure elements in the coastal area (ports, river bases, etc.);
(c) support of Riverine Force in the control of riverine areas;
d) neutralize of hostile forces from the coastal area;
e) support to the Coast Guard in the control of riverine areas;
f) defence against enemy naval and air landing forces;
g) offensive operations as Landing Force for the seizing, securing or control of coastal areas;
h) blocking the enemy offensive river crossing operations in designated river sectors;
i) support to local/central public authorities in civil emergency situations;

As a rule, by their nature, naval infantry small units are light infantry forces, intended for operations by amphibious (air) or combined landings, operating in terrain with major mobility restrictions specific to the coastal zone (delta, littoral, lagoon, island archipelagoes). They are rapid deployable, using a wide range of assets: riverine patrol crafts, combat rubber motorized crafts, civilian vessels as well as air or motor assets (helicopters and vehicles).

In addition to the capabilities specific to military combat operations in the riverine and littoral environment, Naval Infantry small units can be engaged in Peace Support Operations (PSO), non-combatant evacuation operations (NEO), countering unconventional threats (terrorism and piracy) and humanitarian assistance operations (HAO) in the maritime and riverine environment.

The 307th Naval Infantry Regiment is currently trening and transforming for the implementation of standards for amphibious landing force in order to meet the NATO interoperability requirements.
