Avengers: The Initiative #8 (2007)

Killed In Action, Part 1: Snafu
A new batch of recruits, including Cassie Lang (of the Young Avengers), Eric O'Grady (the Irredeemable Ant-Man) and others are introduced to their new trainer, the Taskmaster. The training isn't going all that well, so they authorize the production of additional MVP clones. Unfortunately, at least one of them isn't working out too well, as he has been attacking Initiative members who are on his "list."
