If a card says "Attack (Target Lock): Spend the lock...", then you must spend the lock to start the attack. Same if it says "Attack (Focus): Spend 1 focus token...": you have to spend the focus token to start the attack. Examples include Cluster Missiles and Blaster Turret.

If a card says "Attack (Target Lock):" or "Attack (Focus):" but doesn't tell you to spend the target lock or focus to attack, then you keep that token to spend on dice modification. Examples include Proton Rockets, Harpoon Missiles, and Synced Turret.

Effects like Marksmanship will allow you to modify your dice during any attack that doesn't explicitly ban modification. So no on Snap Shot, but yes on Cluster Missiles and most other attacks. See Modifying Dice.

I hope that helps.
