Is the term "Front Line" outdated?

During Viet Nam, we hac Charlie all around us. No front line, so to speak. Never knew where Charlie would strike from. Today with the Islam radicals, it is just about the same situation. They strike where and when they want to. In front, on the sides, or from behind. The coming World War 3, according to scripture will affect every body and every nation. Consider that North Korea, China, Russia and Iran will unite to take on the world. These countries are pushing right now to start something. Scripture tells how it will start, on a day with two sunrises, like on July morning in 1945 in Arizona desert. This time it will be a city beloved by most people. No, O feel that the "Front Line" concept is history.

Believe it or not our front line is actually in the US. Yes our own CIA funds and trains ISIS. No kidding. So our front line enemy is a domestic enemy. And many in our own gov are wanting this nation to die. Yes die so that their pet project the NWO can be establish. Call be stupid or nuts but read the book None Dare Call it Conspiracy and then tell me I am wrong. Their is our front line.

Sp4 Byron Skinner, The term is not dated, as has flanking, breaking into the enemies rear has either. perhaps the 18th. Century of the Battle line has changed, but at sometime in the future the Line of Battle will be used by some creative American Officers to advance a position who has dug into the study of Military History. The Lines of battle for the ground forces is just two relatively straight lines of 11B's on our side and what eve on the other advancing on each other. It is a basic battle formation. As early ass 50 years ago, the proper way to break a fire fight was to battle line advance. The hope of course the enemy seeing a grouped of pissed off Americans would decide to move in the same direction. I will agree that moving into an enemy in a fire fight requires a definite mind set, if you survive you have bragging rights the rest of your life.

No, it is not outdated. Just because in the OIF/OEF environments the front lines are blurred in relation to 360 degree environment it doesn't mean the next conflict will be as dynamic.

Frontline, Forward Edge of the Battle Area, Main Line of Resistance...., I'm holding out for, Point of Contact for Maximum Dispersal of Ammunition

I would say yes since Koea, Vietnam and so on the front line has really been undefined. Look at the terror attacks of 9/11 and the attacks on the recruiting centers in 2015. Prove that there are no front line to speak of.

Yes, anyplace "outside the wire" is front line.

No. While we may have been conducting pause 4 operations for the past several years, there will again be a time when we fight nations and that will involve taking and keeping large swaths of territory. The men holding that territory will again be on the front line.

Outdated, term I am most familiar with is "Outside the Wire"

No, front line does not have to be terrain-oriented. Whether a Soldier is literally at the FLOT or FEBA or in a firefight a stone's throw from a FOB, that Soldier is on the front line. Unfortunately, the DoD defines the geographic area for hostile fire pay and we, as Soldiers. believe that we are on the front line even though we are not locked and loaded and not moving in a tactical formation.
