calling any artillery '88 fire'

"In real life, Captain Winters encountered a lone German just beyond the perpendicular dike after his solo run, and the 2 enemies sighted each other in time for both to take offensive action. They exchanged hand grenades. But Winters instantly realized as he tossed his, that he had forgotten to unwrap tape from around the spoon before pulling the pin and tossing his. This of course prevented the grenade from exploding. Then, he ran up atop the dike before the German's grenade exploded and fired from the hip, killing the German with his M-1 rifle at pointblank range. Although the German was crouching to avoid the anticipated grenade blast, he wasn't caught totally unaware. People who went back and re-read Ambrose's book after viewing the miniseries version, have asked, why did this scenario need to be changed? Although Winters shot the man, he did NOT gun him down rather cold-bloodedly as shown in the film. Sure, war is ruthless, but this is the difference between beating an opponent who has a chance to fight back, and the rather unsportsmanlike act of killing a surprised opponent who dosn't have a chance to respond. Does it make any difference? He still would've been forced to take him out as shown (because of the company of enemy troops just beyond). But in fact, it didn't happen that way. Perhaps this was changed to avoid showing Winters making any kind of human error, re: the grenade?"

... that Jagpanther could have turned half of that lot to salami before it was knocked out,....

Savage, those are modern hand signals (I think). Look at the helmets, they look like modern kevlar type, and look at the aircraft mentioned in your other link, there were no military helicopters used in WWII.
