The Light Anti-Tank Weapon (acronym LAW) is a weapon featured in Max Payne 3 multiplayer and singleplayer.
The Light Anti-Tank Weapon is a powerful rocket launcher. It is a pre-order bonus, and a part of the Silent Killer multiplayer pack. However, the LAW itself is obtainable in singleplayer without the need of the silent killer pack.
