Story:Star Trek: Intrepid/The Citadel/Prologue

At Starbase 240 the Federation defense fleet are around the base defending the base from a Der'kal attack, in the flight deck of the base Commander Trace is training the pilots on how to take down Der'kal fighters and how to target them.

Commander Torres looks at the Base Commander giving him the run down on the improvements of the defense systems.

Commander since I've got no choice but to have you onboard this base cause of your former commanding officer and current commanding officer stating that you're engineering skills are pretty good, I've wanted to see and I'm guessing it's true carry on Commander Peterson says as he walks away from her.

In the guest quarters B'Elanna contacts her husband.

Hey there honey what's going on at the base? Commander Paris says on the monitor.

She sighs.

I don't know how Typhuss talked me into this he so owes me 5 rounds of Velocity B'Elanna says as she looks at the monitor.

Tom snickers a bit.

Yeah that's true but you are the best Engineer in the fleet next to Commander La Forge and Lefler, but think about it soon you'll be back aboard with your warp core Tom says on the monitor.

Then the base shakes and the klaxons sound.

I've gotta go Tom B'Elanna says as she ends the hail.

A fleet of Der'kal warships are heading towards the base after crippling the defense fleet around the starbase and approaches the base, as the Federation troopers are at the docking hatch as it's being drilled and then several Der'kal troopers and federation soldiers have a fire fight as their being beaten back as they took prisoners and left the base standing but disabled.
