The Grenade, hand, anti-tank No. 74, commonly referred to as the Sticky Bomb, was a British thrown explosive designed and produced during World War II. The grenade was one of several emergency anti-tank measures resulting from the British evacuation from France in 1940, during which the vast majority of its dedicated anti-tank guns were left behind.
— In-game description
The Sticky Grenade is an anti-tank grenade featured in Battlefield V, issued to the Support kit, unlocked at class rank 9. It is similar to the Light Anti-Tank Grenade of Battlefield 1, being a less damaging alternative to the Anti-Tank Bundle Grenade, although it can be thrown as far as a normal Frag Grenade and does not explode on impact with a vehicle.
Instead, it will stick to any object it hits in flight - this may include objects that do not typically interact with grenades, and as such can be stuck to foliage and wire fences. The Sticky Grenade is detonated by a fairly long timed fuse of 6 seconds. As with other grenades, it will detonate prematurely by shooting it.
