What type of munitions does the HIMARS use?

The HIMARS (High Mobility Artillery Rocket System) is designed to use the M31 Precision Guided Missile (GMLRS) and the ATACMS (Army Tactical Missile System), specifically the M48 variant. The M31 provides precision strike capability with a range of approximately 70 kilometers, while the ATACMS delivers longer-range capabilities, up to 300 kilometers depending on the variant. Thus, the correct answer is based on the compatibility of the M31 rocket and the M48 ATACMS with the HIMARS system, which enables it to perform a versatile range of artillery tasks on the battlefield.

For clarity, the other options either incorrectly list munitions that are not compatible with HIMARS or mix the correct and incorrect variants, leading to their rejection as valid answers.
