Reddit user Div2691 picked up on this while trying to destroy a tank using C5 explosives.
Battlefield 2042, like every Battlefield before it, includes throwable sticky explosives.
In this case, they’re called the C5, no doubt a futuristic version of the popular C4.
While you can throw the C5, stick it to vehicles – and even Casper’s drone for a special delivery – the damage values look to be different depending on where the C5 is placed.
