Is the term "Front Line" outdated?

All depends where we are? Since Korea and Vietnam, the front lines usually have been the whole freaking Country. Shit, we even fighting ISIS on the front lines of the USA and around the World! With all of these illegal immigrants coming in, the heavy growth of Muslim population and alike, the bastards are every where! Front lines are right where you encounter these extremist terrorist. Anyplace and at anytime is a front line! That's why we must stay so ever diligent, be aware of our surroundings and not become complacent. People have to learn to report any and all suspicious persons and/or activity at once where ever they are!

Like Viet N am there is no front line. The good guys look the same as the bad guys!

I can't speak to more recent conflicts, but, in my opinion, the term did not accurately reflect the situation in Vietnam...

I think in today's Army the term "Front line" has been replaced with "outside the wire." In a graffical sense, front line is still used.

I don't believe so. There is a difference.

If you are on a FOB and never leave the wire you are not on the front line. If on a COP you most certainly are on the front line.

i would have to say yes on this, with full spectrum combat there are no front lines, the people we fight are in front, behind and minglally with us

"It depends" Time and situation will tell.

Because our enemies can "reinforce" their numbers and inflict damage upon us in our Homeland via the internet, I'd say yes.

But even in the current modes of kinetic warfare, we operate off of firebases located in (ostensibly) key areas where our front line strongly resembles a circle with US forces in the center.

SGM (R) Antonio Brown The day may come when we might fight in more of a "Front Line" war.
