I changed some skill ranks from the last post in my character sheet and added the gear. I didn't add weapons figuring that would happen when the mission is set?
You have both personal and mission gear. Personal gear you buy now. Mission gear you get later.
You should purchase stuff for your personal gear you'd want to have on you in case a mission started on top of you. You receive a number of budget points equal to your Charisma modifier ×5, plus your class budget bonus, plus 40.
