Create an intense and dramatic military march soundtrack with deep war drums and heavy orchestral elements. The music should feature a slow, powerful rhythm with pounding percussion, deep brass, and dark, suspenseful strings. The atmosphere should feel ominous and foreboding, evoking the sense of an army preparing for war. Add subtle electronic pulses for modern tension, but keep the overall sound cinematic and epic. The tempo should be moderate (90 BPM), creating a feeling of relentless movement and inevitable escalation.
