What are, "Vault Cracks" during Spy Missions???

[(NSW)Eon_93 1]

I've NEVER seen that option before during a Spy Mission, until now.. From back when playing on my PS4, to now currently my main console, the Switch. I don't-even know what to search for.... I just did a mission with a random squad, they cracked both (yet, i wasn't there to see it), but i didn't see a damn-thing new on the result screen... So what's up? Please explain to me WHY this option is suddenly appearing, WHAT EXACTLY am i looking for during the mission,  HOW do you crack a vault & WHAT rewards do you possibly get out of it.

 

Appreciate the knowledgeable info. 👍🏾

This didn't help.. Didn't have any information about Cracked Vaults.

Cracked vaults aren't any kind of special mechanic or something, they're just a bit of slang for successfully opening one.

So... What you're saying is, there's no reward for opening one? Therefore, there's no reason for me to go for it?

See if that's the case, I find that hard to believe. The reason-being is because, the party ALWAYS goes for them when the opportunity comes. So there Must be Something rewarding about it.

Opening enemy vaults is Spy's main objective.

You get one reward per vault opened. It's also where to farm for Ivara.

Ohh, I see now. Appreciate it. Finally caught on to me awhile ago.
