strong interrogation about Hellfire and Maverick

power : 18 lbs for AGM-114 warhead is much less than 125 lbs for the AGM-65 D tank killer ?

Does in reality the Apache must use multiple Hellfire to destroy a tank ?

I know it is neutralization which is need but there is a very important difference in the warhead weight !

For armored vehicule or non hardened target Hellfire is a good solution but for tank that’s question me a lot !
