El M79 Osa es un lanzacohetes antitanque yugoslavo, reutilizable, de 90 mm y disparado desde el hombro, construido alrededor de cohetes HEAT no guiados, un contenedor de cohete desmontable y puntería óptica. La evidencia directa de uso en conflicto incluye disparos del Free Syrian Army en Damasco, cohetes y lanzadores M79 Osa asociados al Islamic State en Siria e Iraq, y una incautación por fuerzas de seguridad somalíes en Puntland; el contexto de familia respaldado por fuentes también cubre el RL90 M95, OSA 2 y una carga de cohete termobárica.

Role in Conflicts

2013 War in Iraq
Anti-ArmorInsurgent / Guerrilla Use

CTC Sentinel citó imágenes de Brown Moses de operaciones del Islamic State en Al Anbar que mostraban lanzadores M79 Osa entre las armas antitanque ligeras que llegaban a Iraq, lo que respalda una afirmación limitada de empleo específica de Iraq en lugar de un incidente individual confirmado de disparo.

Designation Context

La familia M79 Osa aparece en fuentes públicas bajo varios nombres estrechamente relacionados, no como páginas de armas claramente separadas. Eurokompozit usó RBR 90 mm M79 - OSA para el lanzador de base de 90 mm, el material croata de historia técnica identifica RL90 M95 como una copia croata del Osa de mediados de la década de 1990, y la cobertura de 2025 trata OSA 2 como una continuación serbia modernizada con nuevas opciones de puntería y cohetes.

Designación de base

Cohete termobárico

Un artículo de defensa dice que Yugoimport SDPR ofrecía un cohete termobárico para el M79 Osa, lo que daba a la familia de lanzadores una opción documentada de carga contra estructuras más allá del proyectil HEAT estándar.

Documented Payloads

Las fuentes públicas muestran la familia M79 Osa en dos líneas de carga distintas: el cohete estándar de carga hueca de 90 mm y una oferta posterior de cohete termobárico.

Cohete de carga hueca de 90 mm

Un artículo serbio sobre innovación militar describe el M79 OSA como un lanzacohetes portátil de 90 mm con una ojiva de carga hueca y una cifra citada de penetración de hasta 400 mm de blindaje homogéneo a 350 m.

Cohete termobárico

Informes de defensa dicen que Yugoimport SDPR ofreció un cohete termobárico para el M79 Osa y que la carga más pesada reducía la velocidad inicial de 250 m/s a 140 m/s.

RPG-7, Reusable shoulder-fired anti-tank rocket launcher, Infantry WeaponsInfantry WeaponsRPG-7Reusable shoulder-fired anti-tank rocket launcherThe RPG-7 is a Soviet-origin reusable shoulder-fired rocket launcher built around a simple 40 mm launch tube and a wide family of over-caliber anti-armor, fragmentation, and thermobaric rounds. Its low cost, portability, and large global stock make it a common infantry anti-armor and assault weapon, including documented Ukrainian service, Hamas use in Gaza, ISWAP use in the 2009 Boko Haram Insurgency, and insurgent use in Afghanistan.
RPG-29, Reusable shoulder-fired anti-tank rocket launcher, Infantry WeaponsInfantry WeaponsRPG-29Reusable shoulder-fired anti-tank rocket launcherThe RPG-29 Vampir is a Soviet-designed, reusable 105 mm anti-tank rocket launcher built by Bazalt for tandem HEAT and thermobaric rockets. Rosoboronexport describes it as a multiple-shot launcher with a 500 m sighting range and a 300-round lifespan, while reference sources place it in Soviet-era development and 1989 service entry. Its conflict record is strongest in close-range anti-armor and fortification attack reporting, including Hezbollah use in Lebanon, insurgent attacks on coalition armor in Iraq, Free Syrian Army imagery in Syria, Hamas anti-armor forces in Gaza, Houthi fielding in Yemen, and documented appearances in Ukraine.
9M33 Osa, Command-guided short-range surface-to-air missile family, MunitionsMunitions9M33 OsaCommand-guided short-range surface-to-air missile familyThe 9M33 Osa is the Soviet command-guided missile family fired by land-based 9K33 Osa vehicles and naval M-4 Osa-M point-defense launchers. The family spans exposed-rail early rounds, naval 9M33M/9M33M1 missiles, canistered 9M33M2 rounds for Osa-AK vehicles, and the later 9M33M3 missile associated with Osa-AKM. Direct conflict evidence is narrow but present: Bellingcat documented Jaish al-Islam launches of 9M33 missiles from captured Osa systems during the Syrian Civil War.

Cataloged conflict records show the system across several generations of air-defense use: Syrian Osa-AK vehicles in Lebanon in 1982, Iraqi SA-8s in the Gulf War air-defense network, captured Georgian systems in 2008, rebel-held examples in Syria, Armenian and Ukrainian battlefield use, and Indian OSA-AK service during Operation Sindoor.

Official Serbian export material presents the RBR M80 as a light infantry weapon for close-range engagements against armored vehicles and fortified positions, while conflict reporting documents Zolja-type weapons in the 2001 Insurgency in Macedonia, Boko Haram materiel evidence, and North Macedonian transfers to Ukraine.

Open-source conflict records tie the system to captured C-90 series launchers in Yemen and to Spain's 2022 military aid for Ukraine, where C90 launchers were documented in Ukrainian hands.
