Weapons in MGS:PO are categorized into lethal and non-lethal, each serving a distinct purpose. Your choice of weapon can significantly impact your mission outcome and recruitment opportunities.

Non-Lethal Weapons:
- Mk. 22 (Tranquilizer Pistol): Your bread-and-butter for non-lethal takedowns and recruitment. Essential for stealth runs. Headshots are instant knockouts.
- Mosin Nagant (Tranquilizer Sniper Rifle): For long-range non-lethal incapacitation. Useful for clearing out distant patrols without alerting others.
- Stun Grenade: Temporarily incapacitates enemies in a small radius, allowing for quick escapes or CQC opportunities.
Lethal Weapons:
- M1911A1 (Pistol): Your starting lethal sidearm. Reliable for close-quarters combat.
- AK-47 (Assault Rifle): Standard assault rifle, good for direct engagements. Can be equipped with a suppressor.
- M63 (Light Machine Gun): High rate of fire, good for suppressing enemies but heavy and noisy.
- M10 (Shotgun): Devastating at close range, but limited ammo and slow reload.
- SVD (Sniper Rifle): For lethal long-range eliminations.
- Grenade: Explosive device for clearing groups of enemies or destroying objectives.
- Claymore Mine: Placeable explosive for area denial or traps.
Always consider the mission objective and your playstyle when selecting weapons. Non-lethal options are generally preferred for recruitment and stealth.
