(1E4) says "each weapon is a separate decision" so if you say "firing disruptor A" and I say "firing photon A" you can then say "firing disruptor B".
However, if you say "firing disruptor A" and I say "no fire" then the conversation ends, and what was declared is declared.
You can "raise" but only if the enemy raised. Once somebody "calls" it's over.
