1 Flag CTF is a variant of Capture the Flag. One team is offense, their job being to infiltrate the enemy base, whether by stealth, brute force, or other tactics, and grab the enemy's flag. Then, the flag carrier must return to the flag stand in their own base while avoiding the other team because they will be trying to get their flag back. The defense's job is quite obvious. Defend the flag, and if it is captured, kill the carrier, and guard the flag until its timer runs down and is returned to base.
