Want to not be mediocre? Train to be a ninja.

I dunno.  They lost to the Spartans in some Spike TV show.

Though admittidly that was BS since the Ninja had both a speed and range advantage... and really the Spartan should of never been within range to deal a blow unless the ninja fought like an idiot.

"Ultimate Warrior" or something...

really assuming tanks and airplanes are out i'd go with "Marine Sniper."

How does the Ninja have range when a spartan has like a freaking 10 foot spear?

Ninjas aren't meant to fight Spartans...

Shuriken?

A) A spartan can't utlize it in a 10 foot strike.

B)

Kusarigama.  The ball can do enough damage to dent a bronze helmet well outside of a spears range.

They actually have the whole thing here.  Though like I said, the Spartan wins, though i'd attribute it to "stupid" AI.

Did Ninjas usually carrry that with them though?

I honestly don't see the logic in a Ninja losing to a Spartan though. The entire show is loony.

General logic was the Spartan Shield would protect the Spartan from all the Ninjas ranged attacks... leading to it having to be a close combat fight where the Spartans sword made the difference.

Yes, I do. I'm quiet most of the time in person unless I know something about the person's personality. I don't want to say something witty or a funny joke and have them not get it or think it's stupid. That's why I keep to myself a lot of the time.

But the ninjas are supposed to sneak up and set them on fire when they're sleeping.

It's the ninja way.
