Funny you mention calling Security. I thought I would have the "Corporate Executive" Call Security for the Fortify or at least say "Call Security"
Some Ideas for you to consider:
IF you want to get real elaborate, you could have her stand up, call security and hang the Phone up for the Fortify then for the Attack she could just stand their watching as a Security Guard comes into the scene and Fights the Battle. The Death could show the Security Guard Death then she could say NO! back up and Drop as she is then also killed
Animating her small part of the same Death animation after the Security Guard is Killed would add a little more length to the Death but that would not be any problem because the Death can be long as there is no other animation after it. Sounds would also work well.
The Security Guard would simply appear and walk into the scene from the edge of the frame for the Attack.
This would simply be another unit as the Security Guard added to the Death Animation. It would also be better to animate the Security Guard Shooting it out in front of her as she stands by watching than animating her calling security over and over. It would also show in a Novel way how and why the enemy died as well as if she dies
She could just stand and watch or you could have her bring her hand up over her mouth as she watches the intense scene, with Hope that the Security Guard will protect her.
The Victory could show the Security Guard walk out (off screen) she looks in his direction and watches as he walks out and says something short such as Thank You, Your Great, Etc... as she sits back down to the Default position.
The Run would seriously be easier and work better if you just show her running without the Desk and when she stops she could be sitting at her desk. I realize that is abrupt to show her Run from her Sitting at the Desk Default and then after the Run showing her sitting back at her desk but a moving desk would be strange. The Run would simply show her immediately Running and the Desk not being there would be understood as she is Running, Not sitting at her Desk.
That said, I suppose you could place wheels on the Desk and add a rolling sound if you want the Desk to be part of the Run. Keep in mind that the Unit would probably need to be set as Wheeled if you keep the Desk in the Run with wheels
