One of the main reasons that prompted the first Su-25 air raids that destroyed the Chechen air force on the ground, and started the Russian intervention, were preparations being performed by Dudayev's air force, which had been spotted by reconnaissance Sukhoi Su-24MRs. There were fears that these aircraft could slow or deter the Russian air and ground campaign, as well as the capability of several aircraft to conduct kamikaze attacks on Russian nuclear power plants (specifically via means of the ejection seat in most aircraft, notably the L-39, by filling them with explosives to act as improvised cruise missiles).
