Where is it?

[skully]

Is it the the Anti-Vigilante HQ that Warp blew up on Rick Flag's orders at the end of Ambush. It was mentioned by Lt Trotter to General Slade Wilson at Fort Ryan at the beginning of Patriot.

No, but you are on the right track. Right scene for the mention

[skully]

An anti-vigilante office?

I assumed it was the one we saw at the end of Ambush?

The only other place that was mentioned in that scene was the Oval Office.
