The M16A1 is an American select-fire assault rifle which feeds from 20-round magazines of .223 Remington (a cartridge that would later become 5.56x45mm NATO). It is essentially an improved version of the original Colt M16 including a forward assist, chrome-plated chamber bore, gas system improvements and a handy cleaning kit. The latter is strictly necessary: as American troops would learn throughout the Vietnam War, the M16 series cannot be reliably cleaned using what soldiers typically do (soap, gas, detergent, insect repellent, dirty water, leaves, smelly socks with holes, sticks with a piece of cloth, etc.) With these improvements the M16A1 was allowed to shine and would go on to become one of the most successful assault rifles in history, competing with the AK-47 for first place. It began mass production well into the mid-1960s, being issued to frontline units (as opposed to prior AR-15 derivatives which were almost always issued to special forces).

Abilities
Common Attributes - Mechanical
Auto
This weapon is fully automatic, either inherently so or by the presence of a selective-fire mechanism.
EFFECT:
This weapon can fire more than one shot each time it is used. Each subsequent shot has a progressive penalty.
Automatic weapons are considered STABLE when they're mounted on a vehicle, tripod or turret. This is different from the Stabilised SA.
- Point Blank Range - No penalty.
- Close Range (≤10m / 2sq) -> -1
- Short Range (≤50m / 5sq) -> -2 (STABLE: -1)
- Average Range (≤200m / 10sq) -> -3 (STABLE: -1)
- Medium Range (≤500m / 20sq) -> -5 (STABLE: -1)
- Long Range (≤1000m / 50sq) -> -5 (STABLE: -3)
~ Beyond this point, automatic fire is unfeasible without a STABLE firing platform. ~ - Very Long Range (≤2000m) -> (STABLE: -3)
- Extreme Range (>2000m) -> (STABLE: -5)
Common Attributes - National
Overmatch - American Small Arms (CW)
