The 9M119M Refleks / Invar is a 125 mm gun-launched anti-tank guided missile round for Soviet/Russian smoothbore tank guns. U.S. Army ODIN identifies the Svir and Refleks family as laser beam-riding ATGMs, Army Recognition describes the 3UBK20 Invar round as intended for T-72B, T-80U, and T-90S tanks, and BDL investor material lists INVAR as a T-90 gun-barrel-fired weapon produced in India under Rosoboronexport technology transfer. In Ukraine, public OSINT imagery documents captured 9M119/3UBK20 missiles in Kharkiv Oblast, while available public evidence does not confirm firing events.

Firing Tank Platforms

Sourced compatibility is strongest for missile-capable Soviet/Russian 125 mm smoothbore tank families rather than for every vehicle that can fire ordinary 125 mm ammunition.

Designation And Compatibility Notes

The 9M119 family is easier to read as a round, missile, and tank-fire-control package rather than as a loose 125 mm shell. Public sources use several names for closely related items.

Reader cueWhat the sources supportReader takeaway
Round versus missileArmy Recognition describes 3UBK20 Invar as the separate-loading round and 9M119M as the guided missile inside that round.The missile-family name and the 3UBK20 round designation point to different parts of the same fired munition.
Svir and RefleksODIN groups 9M119 Svir and 9M119M Refleks under the AT-11 Sniper family; GlobalSecurity separates Svir, Refleks, and Refleks-M as related tank missile complexes.The designations are close enough to read together, but they still mark different family branches and fire-control fits.
INVAR in IndiaBDL investor material lists INVAR as a T-90 gun-barrel-fired weapon for armored targets with Rosoboronexport technology-transfer context.Indian INVAR production sits alongside the Soviet/Russian design lineage rather than replacing it.
Ukraine evidence limitOSINT posts show captured 9M119/3UBK20 missiles in Kharkiv Oblast, but available public sources do not establish a specific firing event.The conflict evidence supports battlefield possession and captured materiel, not a claimed missile employment event.

T-90, Main battle tank, TanksTanksT-90Main battle tankThe T-90 is a Russian main battle tank family developed from the late Soviet T-72B line and built by Uralvagonzavod. This baseline page covers the original T-90 and Russian-service T-90A/T-90AK branch, separating it from the catalog's export T-90S/T-90SA and modernized T-90M records. Direct conflict evidence places T-90A-family tanks with Russian forces in eastern Ukraine and in the full-scale Russia-Ukraine War, and with Syrian government forces and later captured users during the Syrian Civil War.
