Continuing his run of awesome luck, my son's group ran right into an artillery supported sniper ambush. I'd like to sanity check my reading of the indirect fire rules.
Situation: Sniper and spotter are ~30 tactical hexes away when the encounter starts. Howitzer is a 152mm located ~300 hexes away.
Round 1: Spotter calls in a location adjustment from the artillery's pre-plotted "zero". I'm assuming the general area is pre-plotted, since this is an ambush. Rolls a success.
Round 2: Gunner fires. Flight time is effectively zero for a gun 300 tactical hexes away. Gunner rolls 0 successes, so the shell deviates, rolling 1 hex in direction 5, a (very!) near miss. Fortunately, when the sniper fire started coming in to pin them in position, everyone hit the deck -- that plus a little luck means no significant injuries. Everyone in the blast, whether wounded or not, rolls for suppression (and it's no harder for the heavy weapons sergeant who is directly under the blast than for anyone else in the area).
Round 3: Spotter call in an adjustment based on the fact that the squad is (perhaps foolishly) advancing toward the sniper position. Recon check for spotter rolls an extra hit, but this has no game effect.
Round 4: Gunner fires, with 1 hit, resulting in an on target delivery. Each PC rolls for shrapnel hits. One PC takes a shrapnel hit at a C explosive level (based on her hex being 1 away from the epicenter, and her prone position). It hits torso armor, doing no damage because of the Armor +1 of explosions modifying the 1 point of armor from the vest.
Does all that sound correct according to the mechanics as you understand them?
