SP.9 Anti-Infantry Artillery Vehicle

The SP.9 Anti-Infantry Artillery Vehicle was a self-propelled variant of the DF.9 Anti-Infantry Battery, and featured an improved DF.9 laser cannon.

Although meant for long-range anti-infantry support, the SP.9 could also be used successfully against medium and certain heavy armored vehicles. Its rapid fire-ability gave it an advantage over most other artillery units.

Certain features gave the SP.9 unfavourable reviews, such as close-range vulnerability and problematic maintenance and repair procedures (the entire turret had to be removed for engine repairs). Despite this, the SP.9 was credited with the lowest mechanical failure rate of any self-propelled gun in the Imperial Army.

Rebel Alliance ground forces would also utilize only a limited number of SP.9s, due to the space they took up during transport.

Twin SP .9
The Twin SP.9 variant was a self-propelled gun based on the Twin DF.9 Anti-Infantry Battery. Most of the Alliance Twin DF.9s were self-propelled.

The twin SP.9s were covered by a 2.5 cm thick hull, with a light ion unit as powerbase. Like the SP.9, the turret had a 180 degree firing arc. Due to its thinner housing, the Twin SP.9 was more vulnerable than the single-cannon version.
