C.K. Stewart of Newsarama gave A-Force #3 a grade of 8 out of 10, saying, "A-Force gets stronger with each passing issue, and the dramatic turns at the end of A-Force #3 make it the best issue yet." Jeff Lake of IGN gave A-Force #3 a grade of 7.3, saying, "A-Force finds itself in an interesting predicament here in issue #3. The inclusion of a mysterious traitor lends a needed sense of conflict to the book's events, but the lack of substantive development leaves that same reveal feeling slightly underserved. Perhaps it's partly because of the book's Secret Wars restraints, but as of yet the book's level of investment and development doesn't quite match its escalation. Thankfully, this is one example where the book's art is able to mask any narrative quibbles. Jorge Molina turns in another dynamite installment, his clean lines and powerful poses giving added life to C. Willow Wilson and Marguerite Bennett's script. The issue contains a number of standout moments, from dynamic splash pages to more contained emotional beats, and it's through Molina's whimsical, impish quality that the team's still unnamed "friend" remains so intriguing. There's still a lot of potential here, we just need a bit more event book freedom to see it realized." Marykate Jasper of Comic Book Resources gave A-Force #3 a grade of 3.5 out of 5 stars, asserting, "Altogether, A-Force still has a lot going for it, but the pacing is compounding the problems of its large cast. Luckily, issue #3 takes many of the necessary steps for ramping the pace back up, and I'm optimistic for issue #4."
