The protagonist in "Foreign Agent" by Brad Thor prepares for a potential confrontation by equipping his 9mm Heckler & Koch USP SD with a suppressor. This choice indicates a desire for stealth, as he loads the weapon with subsonic ammunition, which reduces noise and avoids drawing attention. He also carries extra magazines, demonstrating that he is ready for any unforeseen escalation.

However, the character reflects on the gravity of the situation; if he finds himself in a position where he needs to use his weapon, it signals a significant breakdown in circumstances. This insight emphasizes the seriousness of his mission and the potential dangers that lie ahead.
