Ah ben depuis le temps que je me posais la question !
TL;DR : dans XCOM 2, l'équipe d'intervention est désignée par l'officier Bradford (aka *Central*) sous le vocable de menace 1-5. Cela fait référence à la convention militaire (américaine ?) de désigner le commandant en tant que "6", soit Menace 1-6 ; Bradford *Central*, en tant que Commandant en second est Menace 1-5. (j'ai l'impression que même en anglais, Reddit est plus clair que moi, je vous invite à aller le lire).

I suspect this has to do with an old military brevity convention where the commander of a unit is designated "6" and the 2IC is designated "5" - it's why the Tom Clancy book is titled "Rainbow Six", because the main character is John Clark, the commander of Rainbow.
In this context, I think C.O. Bradford is usually talking directly to the ranking trooper you deploy in your Menace 1 team. Since you are the ultimate commander of the mission, you are Menace 1-6, and the ranking trooper on the ground who would take over if they ever lost comms with you is Menace 1-5.
This is how I justify Bradford constantly updating the ground team on objectives and developments that you can clearly see yourself by panning your UAV around the map. He's not trying to annoy us, he's trying to ensure the troops on the ground have context in case we ever lose uplink.

That's awesome, never knew that. Any idea why CO is 6?
Edit: found some info here, copied below:

"7= Highest Enlisted Person 6= Highest Officer 5= Executive Officer
At the company level, the 7 is the First Sergeant, the 6 is the commander (a CPT), and the 5 is the XO, a LT.
At the battalion level, the 7 is the Sergeant Major, the 6 is the commander (a LTC) and the 5 is the XO, a MAJ.
At the Brigade level, the 7 is the Command Sergeant Major, the 6 is the commander (a COL) and the 5 is the... shit, I guess it would be the Deputy Commanding Officer, a LTC. Beats me, though."
