Braviary

Initially introduced as a reward from the PvP side of Pokemon Go through its base evolution Rufflet, Braviary is unfortunately mostly a dex entry. Its unimpressive ATK stat and disappointing moveset leaves it little opportunity to shine in the raid/gym attacker scene, especially when much more powerful Pokemon already exist. On gym defense, its Normal sub-typing results in neutral damage from Fighting-type attacks rather than resisted damage, which doesn't help to discourage popular attackers. 

Best PvE Offensive Moveset

• Air Slash is recommended due to STAB and synergy with Braviary's role.
• Steel Wing is a downgrade, TM this.
• Fly is a very strong Flying Type move, and Braviary's best option
• Brave Bird has the silver medal
• Rock Slide is flexible as a 2-bar, but other Pokemon are better Rock-type attackers.
• Heat Wave doesn't have much use on offense. 
• Close Combat is a decent move, but doesn't suit Braviary. 

Best PvE Defensive Moveset

• Air Slash hits harder on defense with STAB, but doesn't provide any coverage. 
• Steel Wing has inferior stats on defense, but can hurt Rock-type and Ice-type attackers. 
• Rock Slide is favorable for defense due to it being a 2-bar move.
• Fly is a solid option, out-pacing Brave Bird on defense most of the time. 
• Close Combat is relatively the same, but at least its coverage is more meaningful. 
• Heat Wave is the slowest Charged Move in Braviary's arsenal

Air Slash gets STAB and sports superior energy generation compared to Steel Wing.

Rock Slide is Braviary's primary charge move due to its lesser energy cost, respectable damage output, and relevant coverage, especially against its weaknesses to Ice and Rock-type Pokemon. Close Combat can also be chosen for its very high damage output and valuable coverage. Brave Bird doesn't get much as use, but benefits from STAB to deal considerable damage. Heat Wave costs too much energy to be viable.
