The altitude for your ingress to target should be low enough to avoid
triggering enemy radar, but high enough to give you enough look-ahead
capability for your RBM (ground radar) so you can steer around ground
threats. The enemy will probably not launch aircraft until a ground radar
locks you up or until you hit your first target, so I don't worry much
about enemy aircraft on the way to target. I have my radar in a/g mode 90%
of the time during ingress, switching to a/a mode only for brief forward
scans.

While you're still "fence out", fly at 2100 feet so you can use the full 80
mile range on your RBM to look ahead for threats. Put the RBM in command
mode (Alt 1 for the pilot's MPCD) and hit <backspace> to target any blips
you see ahead of you. In the daytime, you can "cheat" and hit F10 to see
what you're looking at. At night, you have to guess what it is by the
layout. Groups of three or four blips tightly clustered together are
probably AAA or SAM's. It's a good idea to consider all blips as threats
and find a path where you can weave between them instead of flying directly
over. If you hear a single beep from your TWI while flying at 2100 feet,
immediately drop to 800 feet until you clear the enemy radar range.

Once you go "fence in", drop to 1100 feet (I leave my autopilot on to keep
me out of the dirt). At this altitude you'll have a 40 mile look-ahead
range on your RBM. Continue to steer around ground targets. If you have to
get close to a ground target, drop down to 800 feet or less.

Mountainous terrain can be tough. If the mountains are scattered with clear
terrain between them, my first choice is to stay low and steer around them.
Sometimes mountains are arranged in long continuous ranges and you have to
fly over them. I look for the lowest notch in the mountain range and change
my course to fly over the notch, keeping as close to the mountain as I
dare. This is where you run the biggest chance of triggering an enemy
radar, so head for low altitude the second you clear the top of the ridge.

If you see a square "locked" signal on your TWI, enemy aircraft will be
vectored to your present location. When that happens on ingress to the
target, I hit the afterburner and boogie fast to put some distance from
that point, then I slow down and stop every 5 miles or so to fly a 360 turn
with a/a radar, looking for bandits. Get AWACS reports but don't depend on
them.

When you get within 40 miles of the target (flying at 1100 ft.), turn to
one side so you get a good "squint angle" on your RBM. Hit "S" to see where
your secondary target waypoint is, and turn to that side of the primary
target unless the enemy is more concentrated there. As soon as you get
within 20 miles of the target, drop to 800 feet (you'll still get 20 mile
range on the RBM). Hit <backspace> on the RBM, or generate HRM maps until
you're sure you have the target locked up. Turn directly toward the target
at about 5 mile range. Slow to 70% throttle and pop up to 1200 feet for the
attack. Don't go any higher. If you're getting beeps from your TWI, you
might even try 800 feet (turn hard after dropping slick bombs to avoid
blast damage). Immediately after hitting the target or launching stand-off
weapons, drop to 600 feet, hit afterburners and boogie to a safe position,
then fly a 360 degree turn with a/a radar on to look for fighters. Good
luck!


Additional info on designating ground targets with the RBM:

The easiest way I've found to designate targets is to first put the RBM
(ground radar) in command mode, where it shows the four bright dots under
the display. For the pilot's display, that's <Alt 1>. It's usually  <Alt 6>
for the Wizzo's display. Then hit <backspace> as many times as necessary to
cycle the cursor over the available targets. You can use the F10 view to
"cheat" and see what you're locked on (this only works during daytime).
Note that this targeting technique does not depend on getting an offset
"squint angle" for the radar. If several targets are close together, they
might show as a single dot in your RBM view at 40 mile range. Sometimes you
need to get within 20 or 10 mile range to distinguish individual targets in
a group.

For more precision and for night flying, generate HRM maps. Fly at an
offset to the target so you place it to one side of the HRM display. The
closer you place it to the edge of the radar beam, the faster the map will
generate. When the triangle symbol for the target comes into view, wait
until it comes into the 20 mile range of your RBM, then hit <backspace> to
put the cursor at the tip of the triangle (or use the mouse and right-click
on it). Use "Z" and "X" to set your zoom range, then hit "L" for lock. This
generates an HRM picture. Look for the target triangle... the crosshair
should be centered on it. If it's not, click with the right mouse button.
If you don't see the triangle at all, zoom out and generate another HRM
until you find it. Once you get the crosshair over the triangle, you're all
set. Jump to the pilot position and steer towards the diamond symbol on
your HUD.
