Rules Question - Buying Upgrades

[Veritas]

Page 75 has your answer. You buy each upgrade once for all the mecha on the Force Card. In your first example it will be Valkyrie Squadron (80) + MLOPs (5) = 85.

For your second example, I think you meant VF-1S, because you can't buy a -1J as a Support or Special card. Either way, while it's considered part of the squadron, it doesn't need to take the same upgrades. For instance, my Valkyrie squadron has the MLOPs, while the VF-1S has nose lasers and Gravity Bombs.

For each option, read them carefully. Some options say "gains/gets", others say "change/replace". The former are add-ons to existing weaponry, and the latter replace them entirely. Thus, a Valkyrie squadron can only take one of the first three options.
