I don't know if it's a bug or a feature, but when you throw C4 or IED when laying prone the range you reach with them is doubled! Maybe not doubled but it gets noticeably further than a normal throw, which should be the opposite no?
Found about it when I was laying under sandbags with a pickup shooting at me 2 m away and I tried to toss one at him.
Ended up making my c4 fly way further into the cap point and teamkilling a friendly. 😃
