How do you unlock the M4 Carbine?

The M4 Carbine unlocks at Level 10 in Call of Duty 4: Modern Warfare. It is a fast-firing, low-recoil automatic rifle that works across a wide range of engagements. It is easy to track moving targets and correct onto the head during a burst. Its lower per-shot damage means it depends more on accuracy and sustained hits than the AK-47 or M16A4. Its camo track finishes at Red Tiger (150 headshots with this weapon).

How does the M4 Carbine play in COD4?

RoleFast low-recoil assault rifle
StrengthsFast fire rate and low recoil make target tracking forgiving; Flexible handling works from close to medium range
TradeoffsLower per-shot damage than the heavier assault rifles; Noticeable idle sway can complicate very long-range shots
Useful setupRed Dot Sight unlocks at 25 kills and makes head-level tracking easier during automatic fire; Silencer unlocks at 75 kills for mobile flanking; ACOG Scope unlocks at 150 kills for magnified lanes
Camo tipUse short automatic bursts at medium range and let the fast fire rate correct slightly low opening shots onto the head. Avoid wasting the magazine on distant full-auto sprays.
Compared withIt fires faster and kicks less than the G36C, while the G36C has less idle sway when holding a distant lane.
