[Attack on titan] Could barbed wire work against titans?

Seems like it could be a cheap and safe way to slow and bring down titans, specially the smaller ones.

Maybe the wire would have be stronger than the one intended to stop humans.

Could be quite a good tactic, but you have to remember Titans are often quite bulky and big monsters that blunder headfirst towards their targets.

You'd likely need multiple rows of barbed wire reinforced several times and secured *strongly* to prevent the first 6m Titan from simply stumbling into it, getting wrapped up and pulling it out of its fixtures.

Interestingly enough (given where the series goes) I'd actually think some sort of WWI style trench warfare might work better against Titans. Tons of barbed wire (scaled to work against Titans) and trenches thin and deep enough to allow humans to quickly and safely navigate the battlefield while Titans are impeded by the barbed wire and unable to effectively reach in and grab their targets. From bunkers behind the trenches they can fire cannons and other ranged weapons across no man's land to mow down Titans. Any crippled Titans are finished off when the humans conduct a sweep of no man's land for injured humans and surviving Titans.

This all goes to pot when you involve a special Titan-shifter. It's still way more effective than early AoT open field Titan combat (given the trenches for cover, barbed wire to slow or direct the approach and bunkers for sustained fire), but is certainly only a delay for an intelligent Titan-shifter to avoid.
