You are surrounded by 300 Spartans and can have two pieces of modern day equipment...

[Cabisco]

Nuke and a Nuke shield?

If thats not allowed for some idioitic reason I'd go for modern day tank, i'm pretty sure i'd be unstoppable. Though that leaves some creative room for item two, I think i'd like something to listen to whilst I crush my foes so I choose my ipod.

Spoiler: potential problem with item two

that means no headphones AWWWWWWWWWWWWWWWWWWW

The people that keep saying "modern day tank" and not using the "specify" rule, that and it takes four people to operate the modern tank, 1 to reload, 1 to gun, 1 to drive, and 1 to navigate/lead the tank.

I would take a giant tesla coil to strike fear, and a flame thrower to roast them.

Fine okay then, i'd use a challenger mark 2 that the British armed forces use because it's pretty kick ass and i'm feeling all Britishy and stuff.

*reads rest of post*

Awwwwwwwwwwwwww...

Well keeping with the britishy theme I'll grab an SA80, hold myself up somewhere and hope for a rorkes drift style amount of one sided ass kickery.

 

[Who Dares Wins]

A history book so I could tell them what will happen next and that I see the future. And a machete just in case. (Why yes, I AM strong enough to take on 300 Spartans alone armed just with a machete, thanks for asking)

 

[YawningAngel]

Being as it is rather smaller than an AC-130, I'd like to ask for a tank. A very small one. Failing that, a sopwith camel. Pretty sure that's below the size limit.

 

[Soods]

A Tank and a bottle of coke.

 

[dark_mist34]

jet pack and a bag of grenades

 

[BoTTeNBReKeR]

A G36 and spare ammo (3000 rounds should do I guess).

 

[Calderon0311]

Jackie Chan and a Ladder.
It's a science fact: http://www.youtube.com/watch?v=uZ9DJZAoq3g&feature=player_detailpage#t=157s

You know what? Jackie Chan and anything with rungs basicly. If you can slide, slip, pick up, spin, or use it to get higher, it's a deadly weapon.

 

[The Unworthy Gentleman]

A book and a comfortable armchair. I wouldn't be able to kill the Spartans on my own with anything, so I'll just sit and read before letting them kill me. If I'm lucky, I might be able to sneak off when they aren't looking, but I'll be happy with my book.

 

[TheAmokz]

Flamethrower and riot gear.

 

[Antidrall]

a beam katana and an ipod filled with heavy metal.

 

[Athol]

A Browning M2 .50 cal heavy machine gun on a pedistal mount, with 800 rounds of ammutiotion, and 40 lbs of SEMTEX studded with U nails. If they do kill me the SEMTEX detinator is attached to a dead mans swiitch.

 

[MorteSphere]

A carpet bomber and enough bombs to fill a carpet bomber.

 

[chuckman1]

Well I would have to go with a nuke.
But that's kind of cheating so I'd say a minigun and a China Lake.

 

[Aleos Vance]

HMS Invincible and a really big swimming pool. Hopefully crew is included, or i'm gonna be busy...

 

[Singularly Datarific]

Full sized Main Battle tank
GPMG
Da Spartans be fucked.

Get yerself a Merkava. Only 21 lost to enemy fire, as of 30 years of operational service.

 

[WanderingFool]

One piece is a 30 caliber GAU17

Modified to make it easier to carry, and belt feed by a large ammo drum attached to my back.

Fallow that up with Double Mint gum, double the firepower, double the fun!

 

[Emperor Inferno]

A lighter.

That's it. A simple butane, or liquid fuel lighter. Maybe a zippo.

You see, ancient Greek (yes, Spartans were greek) cultures were extremely religion/mythology oriented, and had no technology like that. Hell, building a fire actually required effort on their part. another thing, fire, in all ancient cultures, was a thing of significance, arcane power.

So, I present to them the lighter and ignite it. they don't understand the fact that it's technology, and believe it's magic. They worship me for controlling arcane power.

EDIT: Or, simply flee in fear of one who can create and control (as far as they know) the greatest destructive force known to man.

 

[LuckyClover95]

When you say surrounded, I'm imagining them all like within a few metres, and no weapon could save me from an army that close. However, if they are say 60 feet away then a minigun so that I could shoot many down and the others would be too scared of my advanced weaponry and run away. I don't know what else I'd need, maybe a flame weapon which is also add fear.

The funny thing is the Spartans basically got killed off because they didn't modernize. They thought "look at that panzy with the ability to kill lots of my men from kilometers away by hurling stones. Fight me like a real man!"

So in all truth these spartans would probably laugh at you as you slaughtered them thinking "If i get closer i can murder the shit out of this little wus with his spinning death machine."

*Her
And I guess.... but they wouldn't understand these weapons, unlike stones, and stuff you don't understand is scary.
