The second factor for the dashed green
line is a jamming resource limitation.
A defensive jammer only has so many
resources available to counter so many
threats. Just because a defensive jammer is effective 1v1 against SA-X, does
not mean it is equally effective 1v5
against SA-X - it does not even mean it
will be 20 percent as effective against
five threats compared to one due to
dwell time and revisit rates required for
effective jamming.

ATTACKING THE SYSTEM
Last, we must always think about attacking an IADS as a whole (a system!),
not as a collection of individual threats -
especially when we are being offensive.
That is, the ability to jam a SAM's Target
Track radar is not attacking the IADS of
which it is a part; it is a part-task attack
on a portion of the IADS. And further,
for SAMs that exist as complexes with
multiple types of radar dedicated to provide the Target Track radar with a track
to engage; if only the Target Track radar is jammed then the remainder of the
complex could still be able to share track

data with another part of the IADS. Conversely, when we are being defensive, it
is natural to focus on the SAM directly
engaging your aircraft, because clearly
that threat is the closest alligator to
your canoe. However, defeating an engagement in an IADS is unlikely to be a
single event from a single axis, which is
why it is so critical to layer offensive EA
with defensive EA. Defensive EA alone
is unlikely to be effective for very long
against a threat kill chain that has been
allowed unencumbered use of their command and control and radar picture.
Figure 1 illustrates the concept that
attacking an IADS must be multi-layered in order to attack, suppress, deny
or delay all parts of the kill chain. We
must integrate offensive and defensive
non-lethal EA along with lethal EA to be
effective in attacking an IADS.
We fail when we allow the dichotomy of an "either or" discussion about
EA. We would certainly not choose to
focus only on offense at the expense of
defense in a BFM (basic fighter maneuvers) sortie, and for the same reason we
must not employ EA against the threat

either offensively or defensively; we
must use both.

TWO METHODS OF OFFENSIVE EA:
STAND-OFF AND STAND-IN
In a military with diminishing livefly training resources in robust simulated IADS, we cannot afford to think
about partially fighting an IADS. Just as
offensive and defensive EA are not mutually exclusive, neither are stand-off
and stand-in jamming. In the context of
this article, stand-off and stand-in EA
are types of offensive EA. The divide between the two is how far into the SAM
Missile Engagement Zone (MEZ) an offensive EA asset will go. In Figure 2,
stand-off and stand-in offensive EA, the
red line delineates a generic MEZ and
the shaded red rectangle indicates the
buffer area where an asset would MEZ
PEN (penetrate the MEZ). Stand-Off EA
assets have been the EB-66C, EA-6A, EF10B, EA-6B, EC-130H, and EA-18G. (I include modified escort EA-6B and EA-18G
in the stand-off category because I am
defining the boundary between the two
as MEZ penetration in a modern IADS. I
