M-4

HA HA M-16s aren't "Machine Guns" they are Assualt Rifles. And the M203 is not the most commonly attached equipment. That would be the M68 Sight and the PAQ-4 Infaread targeting device or the PEQ-2 Infared targeting device that EVERY member of my squad has as opposed to the 2 guys in the squad that have M-203 Grenade Launchers.

In Iraq I killed 6 Iraqis with my M-4 Carbine

M-4

The M-4 is a version of the M-16 machine gun with a 16" heavy barrel which has a special machined groove which is used inconjunction with the bayonet lug, to allow attachment of other devices. The most commonly attached device is a grenade launcher.
This groove is midway between the front sight and the flash-hider on the end of the barrel.

4 A.M. Miracle 

An unexplainable and extraordinary even that happens around 4 a.m. where sleep deprivation erodes your internal censors and allows you to come out of yourself and create something amazing.

If it wasn't for that 4 A.M. miracle, I wouldn't have finished that paper in time for class.

4 A.M Foul

Akin to a party foul, 4 A.M fouls are offenses against your friends, strangers and even yourself. Accumulating too many 4 A.M fouls will usually end with either a.) a severe warning by a friend or aware citizen or b.) an arrest by an officer of the law.

4 A.M Foul #21: Mailbox baseball in your own neighborhood

4 A.M. Foul #40: Entering a bar at 4 A.M already drunk.

4 A.M Foul #3: Waking up in your best friend's bed after a drunken night together and puking all over him/her.

4 A.M. Workout 

The act of working out by having sex with someone.

Workout friend: You want to workout after work today.
Me: No, I had a 4 a.m. workout with my girlfriend this morning.

4 A.M. In L.A.

Tough love, to hold grudges when one's disgusted. Also to make adjustments and while not really knowing who, what, or why.

4 A.M. In L.A. and l had my brightest idea, however they probably would be better if you weren't here.
