Usage in battles

The Strf 9040B excels in ambush and support roles due to its fast-firing autocannon that can severely damage an MBT frontally or destroy it from the sides and rear. However, the Strf 9040B lacks the armour and penetration to effectively spearhead a frontal assault against MBTs and lacks the mobility to quickly reach advantageous spots to ambush approaching MBTs.

When using the Strf 9040B, it is extremely important to manage your ammunition as it only takes 4.8 seconds to completely empty the autoloader, leaving you defenceless. To avoid this, it's recommended to fire in short bursts targeting critical systems and crew. Additionally, it is important to know the crew positions of commonly faced vehicles such as the M1 Abrams, Leopard 2, and Russian T series tanks as they can vary, and the low spall of the Slpprj m/90 APFSDS requires precise aim to be effective.

The Strf 9040B can also carry the Kulsgr m/90 HE-VT round, allowing for the effective removal of low-flying aircraft and thinly armoured vehicles such as most SPAA.

Pros and cons

Pros:

• Decent manoeuvrability
• High fire rate 40 mm autocannon
• Low profile
• HE-VT allowing both ground and air engagements

Cons:

• Lacks ability to effectively brawl MBTs without team support
• Thinly armoured
• 24-round magazine with slow replenishment time
• APFSDS has Low spalling after penetration

History

The Strf 9040B was an updated version of the 9040A, it was updated to meet modern standards at the time installing such things as a fully stabilized gun as well as incorporating new electronic systems. They also made the suspension better as to improve accuracy on the move as well as crew confort. The gun was also upgraded going from the Bofors automatkanon m/70Bb to the Bofors automatkanon m/70Bc that added an electronic firing pin to improve the accuracy of shots. The model was introduced October 1999 and the Swedish armed forces bought about 44 of the 9040B model.
