[300] Hey guys, I know we're all ripped with six-packs and everything, but considering there are swords, arrows and spears aimed at our naked flesh, shouldn't we be wearing armour or something?

I mean, seriously, all we're wearing is capes and loincloths. Surely there's got to be a better way to go into battle...

They were phalanx. Their combined shields made them impenetrable. Anyone dumb enough to step close got a spear. If they got closer they got a sword. There is no need for armor if your shielding was as good as theirs.
