-====== Ammo: 7.62x39mm Soviet/Russian ======+====== Ammo: 5.56x45mm NATO ======
  
 ===== Overview ===== ===== Overview =====
  
-The 7.62x39mm is the iconic Soviet intermediate cartridge, primarily used by the AK-47, AKM, and AK-103 platforms. Compared to NATO 5.56mm, it offers superior **barrier penetration** and raw energy at close-to-medium ranges, but suffers from significantly more **bullet drop** and slower muzzle velocity.+The 5.56x45mm NATO is the primary intermediate cartridge for US Forces. It is characterized by low recoil and high velocity. However, its effectiveness relies on **fragmentation** and **penetration**, both of which vary wildly between the variants listed below.
  
 ===== Modern Combat Rounds ===== ===== Modern Combat Rounds =====
  
-==== 7N23 (BP) ====+==== M855A1 EPR (Enhanced Performance Round) ====
  
-  * **Visual ID:** Black Tip +  * **Visual ID:** Bronze/Silver Exposed Tip 
-  * **Role:** Modern Armor Piercing The "BP" (Broneboynaya) is the modern standard for high-threat environments. It features a hardened steel core designed to defeat modern body armor. +  * **Role:** Standard Issue (Current) The "EPR" is the modern solution to the shortcomings of older 5.56mm rounds. It features a lead-free slug with a hardened steel penetrator. 
-  * **Pros:** Excellent balance of lethality and armor penetration; reliably defeats Level III plates. +  * **Pros:** Best-in-class general penetration; "barrier-blind" (maintains trajectory through glass/wood); consistent lethality against armored AI. 
-  * **Cons:** Harder to find in large quantities; high recoil compared to 5.45mm counterparts.+  * **Cons:** Higher chamber pressure; slightly more recoil than legacy rounds.
  
-==== 57-BZ-231 (BZ) ====+==== Mk318 Mod 0 (SOST) ====
  
-  * **Visual ID:** Black and Red Tip +  * **Visual ID:** Open Tip / Lead Cliff 
-  * **Role:** Armor-Piercing Incendiary A specialized combat round that combines a hardened penetrator with an incendiary charge. +  * **Role:** Carbine / Urban Optimized Developed for the USMC to improve performance in short-barreled weapons like the Mk18. It is designed to fragment on impact while the rear "solid" portion continues through cover. 
-  * **Pros:** Can ignite vehicle fuel tanks and ammo crates (ACE Cook-off); high chance to start fires on impact. +  * **Pros:** Optimized for CQB; excellent "stopping power" on unarmored targets. 
-  * **Cons:** Over-penetrates soft targets; projectile trajectory can be slightly inconsistent at long range.+  * **Cons:** Ballistic coefficient is lower than M855A1; performance drops off past 300m. 
 + 
 +==== Mk262 Mod 1 (SBLR) ==== 
 + 
 +  * **Visual ID:** Black Ring / Open Tip 
 +  * **Role:** Long Range / Marksman A heavy 77-grain Match round. While it lacks a steel penetrator, its mass allows it to retain energy at much longer distances. 
 +  * **Pros:** Highest damage-per-shot in the 5.56 family; extremely stable in high-wind conditions; effective out to 700m. 
 +  * **Cons:** Lower muzzle velocity; poor performance against heavy plating.
  
 ===== Legacy & Specialty Rounds ===== ===== Legacy & Specialty Rounds =====
  
-==== 57-N-231 (PS) ====+==== M193 (Ball) ====
  
-  * **Visual ID:** Plain / Steel Case +  * **Visual ID:** Plain / No Tip 
-  * **Role:** Legacy Standard (Ball) The ubiquitous "Steel Core" ball round. It has been the global standard for decades. +  * **Role:** Cold War / High Velocity The original 55-grain round for the M16A1. It relies on extreme velocity to "shatter" (fragment) upon impact. 
-  * **Pros:** Massive availability; punches through wood and thin metal better than 5.56mm Ball. +  * **Pros:** Very high muzzle velocity; devastating against unarmored "insurgent" type targets. 
-  * **Cons:** Struggles significantly against modern ceramic body armor; inconsistent fragmentation.+  * **Cons:** Virtually zero penetration against modern body armor; loses effectiveness rapidly from short barrels.
  
-==== 57-N-231U (US) ====+==== M855 (Ball) ====
  
-  * **Visual ID:** Black Tip with Green Ring +  * **Visual ID:** Green Tip 
-  * **Role:** Subsonic / Stealth "Umen'shennoy Skorosti" (Reduced Velocity) rounds designed specifically for use with the **PBS-1 Suppressor**. +  * **Role:** Legacy Standard (Pre-2010) The "Penetrator" round used for decades. It features a small steel insert. 
-  * **Pros:** Nearly silent when suppressed; effective for sentry removal without alerting nearby AI. +  * **Pros:** Plentiful in most missions; decent mid-range performance. 
-  * **Cons:** Velocity is roughly 300 m/s. Aiming at 100m+ requires massive hold-over. +  * **Cons:** Infamous for "over-penetration" (passing through targets without damage); struggles against modern Level IV plates.
-  +
  
 +==== M995 (AP) ====
 +
 +  * **Visual ID:** Black Tip
 +  * **Role:** Specialized Anti-Armor Utilizes a tungsten carbide core specifically designed to defeat hardened targets.
 +  * **Pros:** Can penetrate heavy body armor and light vehicle skin (unarmored trucks/technical rails).**Cons:** Very low "flesh damage"; rare availability.

 ===== Deployment Summary ===== ===== Deployment Summary =====
  
-  * **General Infantry:** Use **57-N-231 (PS)** for general purpose work. It is excellent at suppressing enemies behind light cover like wooden fences or foliage. +  * **General Infantry:** Standardize on **M855A1 (EPR)**. It is the most reliable round for 90% of Arma 3 engagements. 
-  * **Elite/Frontline:** Standardize on **7N23 (BP)** whenever possible to ensure effectiveness against armored Western or high-tier PMC factions. +  * **Point-men / Breachers:** Use **Mk318** for superior performance through doors and windows. 
-  * **Saboteur / Stealth:** Use **57-N-231U (US)** strictly with the **PBS-1 Suppressor**. Be prepared for a "rainbow" trajectory and significant energy loss at range. +  * **Designated Marksmen:** Use **Mk262** for a flatter, more predictable trajectory at long range. 
-  * **Anti-Logistics:** Use **57-BZ-231 (BZ)** for disabling soft-skinned vehicles or unarmored technicals by targeting the engine block or fuel tank.+  * **Historical Scenarios:** Use **M193** for Vietnam/80s era kits, but aim for the head or unarmored limbs.
