Is There any disputed knowledge of the battle of long tan?

Nearly ALL battles of ALL wars are, and have been, and will be in the future, DISPUTED. Remember, wars are physical disputes between nations. If they are willing to dispute physically, then they will dispute verbally, as well. Yes, participants from both sides of the "Battle of Long Tan" are disputing casualties, tactics, strategy, etc., as of the 21st century. According to former Viet Cong veterans and Vietnamese historians, 47 VC were killed in action and about 100 wounded. (See: Helicopter pilot Cliff Dohle cited for gallantry in mission to resupply Long Tan diggers, The Australian, October 28, 2009).
