The SdKfz 553 KaiserKäfer with Twin 15 cm sIG 33 Howitzers was a specialized infantry support variant of the KaiserKäfer series, designed for rapid fire support and mobile artillery deployment. Equipped with twin 150mm sIG 33 howitzers, this mech provided high-explosive firepower to suppress enemy positions, fortifications, and entrenched infantry.
Each gun was supplied with 12 rounds, emphasizing hit-and-move tactics to deliver powerful strikes before repositioning. Despite its limited ammunition capacity, its ability to quickly relocate and provide direct and indirect fire support made it a crucial asset in frontline engagements and urban warfare.
A total of 500+ units were produced, making it a relatively rare but highly effective combat mech. Its role in fast-response artillery support ensured its deployment across multiple battlefronts, where its heavy-caliber armament and mobility allowed it to outmaneuver traditional self-propelled artillery while delivering devastating firepower.
