I just imagine a random muggle-born kid in the middle of the Battle of Hogwarts just like
"ACCIO HAND GRENADE!! ACCIO AK-47!!! ACCIO ROCKET LAUNCHER!!!"
And just like three other wizards just flanking him you know casting protective spells and whatnot and he's just there with a machine gun in each hand like the wizarding version of Rambo just
"HASTA LA VISTA, VODLY!!!"
