This is joke right? Last I checked the JP4 has a target size of 17, one less than the 18 of an M8 greyhound. Even if you land the first tulip, usually the second misses. It has to be dead on. Oh, don't forget top secret Nazi camo phase armour. Activate it in combat and you are invulnerable to tulips, attack ground, and mines.
Tulips hit cloaked tanks.
Idk about target sizes (target size is just value for accuracy calculation and not an actual hit box size, isnt it?), but i have numerous jp4 snipes from full health on my fireflies. It can also miss if you fire tulips from low-ground to hight-ground, but tulips always tricky to use.
