From May 20 through June 3rd, there is to be no discussion of US politics. All existing threads on the subject will be closed. People can start new ones once the hiatus is over. See the thread in Trouble Tickets for more info.
I thought there's a "standard kit", mate?
Otherwise... night vision goggles, rifle (you pick me a model from the setting), 9mm Glock 17 (or 10 mm S&W, if the money are enough), spare clips, Bolo knife (or a karakulak, khukri, or yatagan, they're quite similar), breathing mask, bullet-resistant armour, 2 EMT grenades. And if there are liquid nitrogen "grenades", I'll have another few. Freezing and breaking FTW!
Add to it one of those supple saws and anything that helps you hide and/or sneak, spare clips, and I'm set!
