You do get repeats so be careful, next Spec Ops will start a while after these 8 days.
In Spec Ops 7 you can still get Lockboxes from deploys
7.1 the black cat and war machine deploys have lockboxes
7.2 Sif, Ms. Marvel and Invisible Woman deploys have lockboxes
7.3 Spider-Man, Cable and Wasp deploys have lockboxes
get to it gentlemen, good luck.
