The two front men started every one of Bosnia's 10 qualifying matches as Safet Susic's men reached their first ever finals as an independent nation by topping Group G on goal difference ahead of Greece.
The squad was cut from an initial 24 - owing to an injury concern over Mensur Mujdza, who made the panel at the expense of Gent's Ervin Zukanovic - on June 2.
Two men who were always sure to be included in the final party are Dzeko and Ibisevic, who will spearhead the Bosnian attack after scoring 18 times in qualifying between them, while Stoke goalkeeper Asmir Begovic will be a key member at the other end of the field.
Susic discussed the inclusion of Ferencvaros' Muhamed Besic, praising the defender's performances for his club side.
"He is the only player who can stop Lionel Messi," he is quoted as saying by Klix. "I have had no problems with him, he's playing wonderfully in Hungary.
"He's a good guy and I think he has a bright future when it comes to the team.
"Our goal is to pass into the second round. Whether we realise it, that's another thing. I do not believe that Nigeria and Iran are a better team at the moment. I hope we can be among the top 16."
