Does the use of General Weiss apply Arsenal 2 to every miniature in your army? It sure reads that way.
General Weiss: "Until the end of your activation, you gain Arsenal 2. (While attacking, each of your minis can use up to 2 of its weapons)." Note that his is clearly worded differently than the standard Arsenal 2 definition: "(While attacking, each mini in this unit can use up to 2 of its weapons.)" It seems clear they intended something different with General Weiss than the standard Arsenal 2... and the key part of that appears to be "each of your minis" not "miniatures in this unit"....
This would mean that both AT-ST's in an army could use all four of their weapons when General Weiss activates (not just the one he is in), which seems to be what they intended, but I thought I would ask. I didn't see another Rules topic covering this particular point either.
