C4

In Tom Clancy's Rainbow Six Siege the C4 charge is the Nitro Cell, a remote-detonated explosive built as a killing tool: a detonation deals up to 171 damage within 2 metres, dropping rapidly to nothing at 6 metres, and it also damages through breakable surfaces. It sticks to objects, so defenders place it above doorways or below floors to catch attackers, though a placed cell beeps quietly and shows a red light, pulling one out makes a small ripping sound, and it uses a heavy throw that does not travel as far as other throwables; a direct hit does 5 damage.
