Also tanks in Vietnam were used as both the hammer and the anvil on Search and Destroy missions, being fast enough in even the worst terrain to outflank and outrun guerrilla and sturdy enough that one tactic used was for the tanks to advance firing automatic weapons in order to flush soldiers waiting in ambush until the tanks acting as containment (and crew safely stationed inside their vehicles) reported bullets boincing on their armor.
In particular the M60 was liked for its survivability to most handheld weapons and light artillery at even point blank range which at worst managed mission kills and light damage, and was part of the reason unexploded aviation bombs were converted into antitank mines.
i read about how japaneese use them - they bury bomb/100kg or bigger/ with mine on it,when tank come,both blow up.
