How to Force Next Wave

I apologize, but I am very very new to how Arma 3's coding system operates. Is there any way for me to force the wave to end in order to spawn the next wave? Frequently I find myself with too much downtime between waves as I try to track down the ever teleporting last unit.

I believe I can do this by clearing the MustKill array, or calling the StartWave function, but please let me know if there are simpler ways, such as just mass killing the enemy team with a command.

Again, I'm not familiar with how to execute code in Arma yet, so I would appreciate a step-by-step walkthrough, if you could provide it, thanks.
