====== Ammo: 5.45x39mm Soviet/Russian ======

===== Overview =====

The 5.45x39mm is the modern standard for the Russian Armed Forces (AFRF). Designed as a response to the NATO 5.56mm, it features a high velocity and flat trajectory. It is famous for its "poison bullet" effect—an extreme tumbling (yaw) upon impact—making it devastating against unarmored targets even with standard ball rounds.

===== Modern Combat Rounds =====

==== 7N10 (Enhanced Penetration) ====

  * **Visual ID:** Purple/Violet Ring
  * **Role:** Standard Issue (Current)
  * **Description: **The 7N10 is the primary "improved" round for modern Russian infantry. It features a lengthened steel core to bridge the gap between ball and armor-piercing rounds.
  * **Pros:** Good balance of availability and penetration; reliably defeats mid-tier body armor.
  * **Cons:** Struggles against heavy Level IV ceramic plates.

==== 7N22 (Armor Piercing) ====

  * **Visual ID:** Black Tip / Dark Ring
  * **Role:** Specialized Anti-Armor
  * **Description: **The 7N22 utilizes a hardened high-carbon steel penetrator. This is the direct answer to high-end NATO body armor.
  * **Pros:** Excellent armor penetration; maintains lethal energy through light cover (plywood/car doors).
  * **Cons:** Rare in common stockpiles; slightly lower "flesh damage" due to the rigid core design.

==== 7N24 (Super Armor Piercing) ====

  * **Visual ID:** Black Tip / Specialized Markings
  * **Role:** Elite Anti-Armor
  * **Description: **Often referred to as the "Tungsten" round, the 7N24 features a tungsten-carbide core for maximum penetration.
  * **Pros:** Will punch through nearly any infantry-scale armor available in RHS.
  * **Cons:** Extremely rare; tends to over-penetrate unarmored targets, resulting in lower immediate "stopping power."

===== Legacy & Specialty Rounds =====

==== 7N6 / 7N6M (Ball) ====

  * **Visual ID:** Red Ring / Plain
  * **Role:** Cold War Standard
  * **Description:** The original 5.45 round. Famous for its internal hollow air pocket in the tip that causes the bullet to tumble immediately upon impact.
  * **Pros:** Devastating soft-tissue damage; extremely high fragmentation in unarmored targets.
  * **Cons:** Very poor penetration against modern ceramic ballistic plates.

==== 7U1 (Subsonic) ====

  * **Visual ID:** Black Tip with Green Ring
  * **Role:** Subsonic / Stealth
  * **Description: **Specifically designed for use with the **PBS-4 Suppressor**.
  * **Pros:** Nearly silent; eliminates the supersonic "crack," allowing for covert sentry removal.
  * **Cons:** <wrap alert>**Severe trajectory drop.**</wrap> Muzzle velocity is ~300 m/s. Effective range is limited to <100m.

===== Tracers & Signalling =====

^ Type ^ Matching Round ^ Notes ^
| **7T3** | 7N6 / 7N6M | Green tip. Standard Soviet tracer (Green trace). |
| **7T3M** | 7N10 / 7N22 | Improved tracer with longer burn time and better ballistic matching. |

===== Ballistic Comparison Table =====

^ Round ^ Weight ^ Velocity ^ Armor Pen. ^ Soft Damage ^ Ideal Range ^
| **7N6M** | 53 gr | High | Low | Very High | 0 - 350m |
| **7N10** | 56 gr | High | Medium | High | 0 - 400m |
| **7N22** | 57 gr | High | High | Medium | 0 - 400m |
| **7N24** | 63 gr | High | Extreme | Low | 0 - 350m |
| **7U1** | 80 gr | Subsonic | Very Low | High | 0 - 100m |

===== Deployment Summary =====

  * **Frontline Infantry:** Standardize on **7N10**. It is the most versatile round for the modern "armored" AI meta in Arma 3.
  * **Special Operations:** Prioritize **7N22** or **7N24** for missions where heavy Western-standard plate carriers are expected.
  * **Stealth Infiltration:** Use **7U1** only in conjunction with a **PBS-4 suppressor**. Ensure your optics are zeroed specifically for subsonic velocity.
  * **Machine Gunners (RPK-74):** Use a mix of **7N10** and **7T3M** tracers to walk fire onto targets at range.
