A painter
A painter is a sneaky soldier who sneaks into the enemy's backyard to plant a glowing target that the enemy can see but can't find. It’s like a cursed blinking light that only the allies can see.
Hey, I saw the painter last night. He looked like a madman with a laser pointer.
The enemy was confused. They saw the target but couldn’t find it.
The painter got caught and got yelled at by the enemy commander.
