Variant of the term Battle Rattle. In this case it means wearing a suit and tie. This phrase is likely used by veterans who try to avoid wearing suits but are in a profession that requires wearing a suit.
Because we are meeting with the CEO of the company, we need everyone in professional battle rattle for the meeting. No Jeans, or T-Shirts with funny pictures folks.
