Meaning of との in this sentence?
It's a case particle と ("with" as in "face with something" or "fight with
someone") followed by a noun-linking particle の. See:

  * [using の with と,で, から, まで](https://japanese.stackexchange.com/q/33605/5010)
  * [What is this との?](https://japanese.stackexchange.com/q/54461/5010)

Assuming this sentence is said in a common fantasy RPG-like setting, 後衛との壁
refers to either of:

  * the wall (tank) that blocks ranged attacks (e.g., arrows) coming from rear members of the enemy
  * the wall (tank) that guards rear members (e.g. supporters, healers) of the ally

The former is more likely but it may mean the latter depending on the context.
