CBS is deploying SEAL Team for a full season, ordering nine more episodes on top of its original commission after what's proven to be a strong first three weeks.

The Navy drama, from CBS Television Studios, stars broadcast staple David Boreanaz — a man who, for those not keeping track, has been the lead on a TV drama (Buffy the Vampire Slayer, Angel, Bones and now SEAL Team) every year since 1997. SEAL Team has made a strong impression on Wednesday nights, averaging 12 million viewers and a 2.0 rating among adults 18-49 during its first two episodes. The most recent live outing averages a 1.5 rating in the key demo and 8.9 million viewers.

SEAL Team joins fellow CBS freshman Young Sheldon as one of the few new fall series to already receive a back-nine order. ABC gave a similar five-episode green light to The Good Doctor last week.

What's most interesting about the moderate success of SEAL Team is that it's an outlier in the otherwise ho-hum narrative about military shows this fall. NBC's The Brave has done decent enough on Monday nights, but, compared to previous 10 p.m. occupants, it is squandering its post-Voice time slot. And though word is still out on how The CW's Valor will perform on other platforms, its initial linear draw was lackluster. These shows are an especially tough sell internationally, so success by more traditional metrics is key.

The new season has been a fairly good one for the broadcast networks thus far. Everyone has a hit or two to hang their hat on. But it's a little odd that SEAL Team is only the third series to get a formal vote of confidence. (This is excludes NBC's Will & Grace reboot and Fox's The Orville, each of which got a full (shorter) season to begin with.)

SEAL Team also stars Max Thieriot, Neil Brown Jr., AJ Buckley, Toni Trucks and Jessica Paré. Benjamin Cavell, Ed Redlich, Christopher Chulack, Sarah Timberman and Carl Beverly are executive producers.
