Why couldn't the Solver just give the DD actually advance armaments?

I mean Lord Almighty, Khan's Bunker Doors is so painfully thin for a bunker meant to stop Robo-Armageddon. (N held the first door and it fits right in the palm of his hand)

I'd seen Banks Vault doors Thicker than that.

Us Humans today literally have thicker Armor plating on some Mobile Tanks than Outpost-3's First and last defense.

A standard Anti-tank weaponry from WW2 could actually penetrate that sorry excuse of a Door, I'm not even joking.

Can't the AS just give the DD Armor-Penetrating Rounds instead of V clawing her way in for months?

Better yet, the AS could just Dropshipped a Portable AP Turret to each DD squad Helldiver style. (Why not? It sends 2 dropships carrying "Tessa's" unnecessary accessories)
