Yak-130 and its clones: M-346, T-100, and L-15. Is the Yak the only weaponized one?

all have the same lineage, although different airplanes I guess.
all claim to be able to do some combat and posed with various munitions

but as far as operations goes, it seems only the Yak-130 is being used for non-trainer, combat roles.

were the combat capabilities for the Yak clones just advertised and never implemented?

i heard the L-15 for some African country even had a pesa radar!
