Weakest Fictional Army that can get past the Great Wall of China (The Great Wall

[Iron_Twister]

Got around to watching The Great Wall this week and came to the conclusion: the Great Wall of China is one Hell of an obstacle to tackle. Numerous troops manning every inch, war machines of various forms, and crazy prepared tactics.

It's no wonder why an army of killer monsters opt to dig under the wall than to send wave after wace to assault it

So biggest challenge here? What is the weakest army in fiction that can get past the wall by means of assault? Let's say winning move is that a single foot soldier manages to get to the other side of the war.

The army of choice will have their equipment and numbers as depicted in their source material.

The Great Wall will have the Nameless Order at full strength. For kicks, lets just add Matt Damon's character and his pal in as well.

Well I don't know how it worked in that show, but in real life the invaders just bribed the soldiers to lower ropes and let them climb over. So I'll go with Marcus Licinius Crassus's Army.

EDIT: Oh wait, he wasn't fictional... Ummm... Horrible Histories version then, where he's a rapper too.
