Usage in battles
The Osa-AK is a clumsy and slow vehicle and thus should be kept behind cover, it has minimal armor protection and will not sustain direct fire for very long. It's missiles are powerful but hindered by a poor horizontal turn radius. While its radar is effective, with multiple search options, it has limited sweep speed and will struggle to find multiple targets quickly, its best to use the 45km sweep to prepare you shots in advance.
Pros and cons
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".
Pros:
- Powerful 9M33M3 Missiles with good G-tolerance and speed, able to take down targets in a single hit
- Five crew members allow you a little flexibility when taking strafing fire.
- Amphibious and able to set up in sneaky water positions
- The crew is situated in the front half of the vehicle, leaving dead space in the back half, shots will do little damage here
Cons:
- Abysmal Horizontal turn speed, make sure to set up in opportune areas to avoid missing your attack windows.
- Slow vehicle with an underwhelming engine, will struggle to climb even small hills.
- No armor protection whatsoever, nearly every shot is lethal to it.
- Only six missiles with an abysmal reload time (Ammo box and replenish is required) with only 3 missiles reloaded per stage.
History
The 9K33 OSA is a low altitude, short-range tactical SAM developed by the Soviet union in 1960s. Units entered service in 1972. It is air transportable, and was the first mobile air defense system to use TELAR, which can detect, track and launch against hostile aircraft independently without the aid of additional radar. The vehicle was exported and use by most members of the Warsaw pact, including East Germany and Poland. It is still used by the Russian army today and has seen active service in the Ukraine Conflict.
