OVERVIEW: 90mm rockets are unguided munitions designed for air-to-ground and ground-to-ground use, offering greater destructive power than smaller-caliber rockets. They are used to engage infantry, light armor, buildings, and field fortifications through blast and fragmentation effects delivered in saturation fire.

DETAILS: The 90mm rocket typically uses a solid-fuel motor. It is commonly launched from multiple-round pods or rails mounted on helicopters, aircraft, or light ground vehicles. While lacking guidance, its larger warhead compared to smaller calibers gives it improved lethality and area effect. These rockets are particularly useful in close air support and suppression roles, especially in counterinsurgency and open-terrain engagements.

ROLE SUMMARY:
Category: Unguided Rocket
Primary Use: Area suppression / Anti-personnel / Anti-material
Function: High-explosive fragmentation via short-range rocket saturation
Strong Against: Infantry, soft-skinned vehicles, field positions, light structures
Weak Against: Heavy armor, hardened bunkers, targets requiring precision
Platform: Attack helicopters, light aircraft, ground-based launchers
Integration: Compatible with 90mm rocket launch systems and pods
