How would you defeat this?

Some context: This is my stack, with basically all my units. The enemy was spamming infantry, so I decided to push straight for their homelands and basically force them to fight me instead of them being able to attack me from all sides. I am trying to see weaknesses in this stack. I know MRLs will destroy this stack if I am AFK, but I think if I am active, I can probably outnumber the MRL, and because I have 1.5x speed, I can easily get in range to fire at them. It is day 48 currently.
