B2 Rocket Troopers exact timing

[ovinomanc3r]

What is this card exact timing? Can I choose to resolve it after the defender spent its defense token in order to know in advance if I want to prevent him from resolving a Concentrate Fire Command Token cause he spent a Salvo Token or another command if he didn't?

It is not a modify dice or spend accuracy effect so I don't see it necessarily linked to the Resolve Attack Effect Step of the Attack.

Thanks!
