You're a Spartan in the Halo universe. You're in the middle of a battle that does not look like it'll go well. Most of your team is dead or wounded. You're low on ammo, and the Covenant are everywhere, destroying buildings, killing civilians who are taking cover

then you hear something two Spartans run out from buildings, their armours reminding everybody of old crusaders as they wield swords, running out into the battle, blaring "Sanctified with Dynamite" from their armour
