Usually, at the beginning of a game in tiers around 11.0, speed is an important factor, especially for fighter-bombers, and planes like the Tornado, MiG-27, MiG-34 and others, always spawn with their speed almost at the top, around Mach 1.0, but, the Su-24M, despite being an attack aircraft with excellent performance, its air spawn always starts at 800kph, so most of the time it will never manage to bomb more than one base, even though it has the capacity to destroy 3.5 bases.
It has good potential, but due to this small detail, a difference of 300kph compared to the rest of the planes makes it impractical.
