MiG-29 Avionics

I am interested in the following MiG-29 varients for Algeria

MiG-29S/UB
MIG-29SMT

I am trying to identify the exact names for the following components that are mounted on these MiG-29s.

IFF – SRO-2 (NATO ‘Odd Rods’) IFF transponder and SRZ-15 interrogator
HUD – Shchel-3UM helmet-mounted sight
Flares – SUVP-29 passive countermeasures control unit; BVP-30-26M dispenser, with 30 PPI-26-1B 26 mm chaff or flare cartridges, in each fin root extension.
Jammer -Two SO-69 ECM antennae
Radar Warning Reciever -SPO-10: H- through J-band airborne analog radar warning receiver OR Sirena 3 SPO-15LM (L006LM Beryoza) 360є radar warning system
Electro optic targeting device – S-31E2 KOLS Infrared Search and Track (IRST) OR OEPS-29 IRST/laser ranger.

Can anyone assist with the OR catagories? I am stumped.

Thanks
