A look at explosives and bombs ratings

[Imp]

Some thoughts here

The standard WinSPMBT Booby Trap is apparently a weak 120mm mortar round (1/2 the HEK)

Seems to work pretty well more chance of a suppress result than a kill, representing caution looking for it. Oops did get a kill fond it in that 50metre hex.
.

Your friendly neighborhood Suicide Bomber apparently packs the equivalent of an 81mm mortar shell with twice the explosives (HEK rating)

If he survived can assume he detonated on top of target?

Your average IED is a Fertilizer Bomb ... and an impressive bomb it is !
It compares VERY favorably to the standard 1000kg aerial bomb !

Okay possibly another smaller one should be available but doable with diesel & a few extras, tricky bit is hidding it & having the blast hit effectivly.
