Double Subverted: Bob constantly talks about how he can't wait to fight, putting him at odds with Alice. When the time for the battle arrives, Bob decides that it's a better idea to stick to the plan. A minute later, he decides that waiting is boring and charges ahead anyway.
Parodied: Bob charges the enemy and his friends expect him to be killed, turning away in horror. They open their eyes when they hear the enemy retreating in fear of the single soldier attacking them.
Zig Zagged: Bob rushes the enemy by himself without fear of death or any kind of plan, but this is a distraction planned out by his superiors who use his charge to get the drop on the enemy. However, Bob did not know about this plan and the 'distraction thing' was Xanatos Speed Chess on the part of his superiors.
Averted: Bob is a well-trained soldier who doesn't want to die and as a result, spends most of the battle crouched behind cover.
The audience expects Bob to charge the enemy army, so the writers make him do it.
The results of the battle were decided by fan voting even though the enemy's forces are outclassed and their general's leadership skill is sub par. The author thought this trope would be the best way to justify Alice losing.
Lampshaded: "He just had to run in there and get himself killed, didn't he?"
Reconstructed: Bob is a distraction. By running forward and screaming his head off, he attracts attention away from the main force. If the enemy sees through this ploy and ignores him, Bob has orders to accomplish some other objective. Thanks to his charging force, his team's objective is fulfilled but Bob is still "stupid as hell" for volunteering for such an assignment.
