Q makes it look easy.
The hard part was 'setting the stage'.
All the hard work and long hours were done prior. It wasn't a take out an asset here now, take out an asset there later.
It was a 'HIT THEM WITH ALL GUNS AT ONCE' and kill them with one super-charged knockout blow.
Movies and drama novels like long played out fights.
This was a truly tactical war move. One punch. Make it count.
