The Su-30 in Battlefield 2 fullfills the role of a strike fighter for the PLA and as one of the three fixed-wing aircraft operated by the PLA (J-10, Su-30, Q5 Fantan). Its counterparts are the USMC and EU F-15E Strike Eagle, and the MEC Su-34 Fullback.
Like its counterparts, it has an armament made to take out soft targets and armored vehicles on the ground (five high-drag bombs and six-teen air-to-ground missiles) rather than for dogfighting (only four heat-seeking missiles compared to a fighter jet's six).
The Su-30 should be used to support ground troops by bombing concentrations of enemy ground forces. Another player that controls laser-guided missiles for destroying ground armor can enter the Su-30, further improving its anti-surface capabilities.
Like other fixed-wing aircraft, the Su-30 is a considerably high threat to helicopters, as a short, well-aimed burst of cannon fire or two air-to-air missiles will destroy it, coupled with the aircraft's speed. It is most recommended to fire a burst of cannon fire on the first attack, as the opposing helicopter may have flares ready, which can be used to cause air-to-air missiles to miss the target.
