US Army Cancels Comanche Helo

The matter of using MLRS for SEAD for AH's brings up
the question of whether it's sufficient for saturating
the defences. While anti-personnel bomblets, like
those used in MLRS, cluster bombs and such, typically
are very effective, there are situations where this
isn't the case. Soft terrain, like snow covered ground,
or boggy ground, greatly reduces the effect of any impact
fuzed arty, and small muntions in particular.

Firstly, the submunitions may fail to detonate, as the
decelearition when hitting the soft terrain may be
insufficient to trigger them. Secondly, the effect of
those that do detonate, is greatly reduced by the snow
or bog absorbing the blast and sharpnel. And finally,
there'll be no bouncing, which otherwise could give
bomblets a kind of low-level airburst capability.

Airburst by proximity fuzing is the obvious solution, but
I think it'd be prohibitavely expensive with bomblets. In
forested terrain, 'trigger-hair' impact fuzing may give
canopy-level airbursts, but I guess that wouldn't be practical
with bomblets either.

Are there bomblets (anti-personnel submunitions) that
actually work well in soft terrain? And if so, how
do they accomplish it?
