Default point and shoot video, by radar

this is a video of the point and shoot technique using just the radar. its 153 mbs.

i believe this is the first video of a convoy being attacked by the use of radar only in sh4, it has been proved that the point and shoot technique works visually, and with the hydrophones,
how we can add tha radars to the list of sensors that can engage and destroy targets.
the target was a 10 ship convoy, closing, four escorts and 6 merchants, i targetted two merchants with two torpedoes apiece, missing one target with both torpedoes,
but hitting the other and sinking it with both torpedoes, of which one was a dud. the kill was a modern passenger liner, MPL.
there is no narration in the film itself, just the crew voices, i have no mic, so ill have to explain here.
it was a night that was very dark, (pacific e), around 23:00, torpedoes were set to 12 ft, contact fuse. submarine at 39 ft depth.
the target destroyed was at a range of 1.09nm at torpedo impact, or 2000 yards.

mods that i think were essential in making this shot were:
pacific e 4, for the night to be so dark.
trigger maru camera. dat file. im running stock 1.5, but took alot from tm, the cam dat file lets me zoom into the radar screen, and breeze around the sub, just like the tm users do, works great in stock.
hi rez radar screen, great precision, very accurate!
small radar contacts.
if not for these mods, i dont know if the shot would be possible, but with them it is, so thanks to these modders

ok, the situation,
i have made radar contact with a convoy off the port side, range about 36000 yards, i followed the first step in the point and shoot technique by determining the convoys AOB,
by its relative movement, which would take it pass the port side of the submarine to the rear. it has a port AOB, so i reversed speed, and went hard to starboard, which would bring the convoy to the second step of the point and shoot
technique, which is to get the target on an eighty degree offset. i would attack this convoy on its left flank.
i turned until the destroyer at the point was on a bearing close to 80 degrees, once i got the point destroyer at or near 80 degrees, the convoys course was basically 270
relative to the submarine.
at about 16000 yds, i took a speed estimation, starting the watch, estimating the distance of 1000 yds on the radar screen, and watching the second ship in the first column, in about 4 minutes i stopped the clock, and plugged those figures into the TSD formula
4 minutes at 1000 yds, gave a speed of 7.4 knots. the firing bearing would be 13 degrees starboard.
now, all that was left was to let the convoy proceed on its course, taking it across the firing bearing of 13 degrees, and striking the targets at zero degrees.
shooting at the farthest ship in the first row across, last column, just to see if i could hit it with radar, and then the second farthest ship.
i dont know which one i hit, because after the fourth torpedo was fired, i went to normal dive, and listened in the hydrophones for the explosions.

the really nice thing about this tutorial, is that you can plainly see the ships, and the procedure of the point and shoot technique, how really simple it is, how lethal
it is also.
"it was easier in real life" said jurgen osten, this proves it i think
