True. What I meant to say was that the 73mm only has an *immediate*
impact 
fuse - ie., doesn't have any *delayed* impact setting which would allow
it 
to penetrate some way  into the berm, and even through thin brick 
walls/concrete slabs, before exploding.

(For some reason I can only recall the Swedish terms for the fuse types
and 
have to make do with roughly translating them into English >:-( )

Other types of shaped-charge rounds do have this kind of delayed impact 
fuse, though they're usually called "bunker busters" or "HEDP" or
something 
similar rather than "HEAT". Still, some (IIRC most!) of these rounds
have 
better armour penetration than the old 73mm :-)
