Just enough info to be interesting, but not enough to prevent an aneurysm with everything that is so glaringly WRONG with the “military details” and descriptions in this story.

Vampires on a submarine in 1983 during an extended deployment to Russia? Amazing idea. But as a former SONAR Tech, I’m going to use my DD214 to nitpick here…

1) The prologue had me scared that this was going to be horror-themed smut. Glad I was wrong.
2) Unless these vampires have bioluminescence in their irises (which makes no biological sense), her eyes would reflect, not glow.
3) “Poopy-suits” is the name of disposable coveralls worn while doing the “poopy” work. The blue underway coveralls are normally called, wait for it, “Coveralls”.
4) Officers wear the Coveralls, too.
5) Unless this is a Surface vs Sub thing, they’d have no need to go to red. The red lights are for night time use, to reduce the chances of being spotted by enemy vessels as red light is harder to see at a distance at night.
6) The author goes on at length about the Navy abbreviations of everything, and then proceeds to never abbreviate anything further in the book, except for OOD and COB (whatever that is).
7) Three chapters after the abbreviation rant, The Hospital Corpsman (yes, that’s how it’s actually spelled) is finally shortened to Corpsman. This is in spite of the fact that all sailors call their corpsman, “Doc”.
8) There is NO WAY that a ship would be deployable if Doc was the ONLY person onboard trained to handle medical situations. EVERYONE onboard actual ships are First-Aid and Triage trained. The Med Bay is small (but fully stocked for everything short of a birth) because the Mess Decks are supposed to become a Triage Ward in the event of a Mass Casualty. I’m also fairly sure that an LA class would have at least one more corpsman onboard.
9) Our protagonist, STS1 (another common actual abbreviation that isn’t ever used), claims that all he’s looking for on SONAR are ships and other subs, despite stating later in the book that the sub runs blind. It doesn’t, though. SONAR is the sub’s eyes, and the SONAR Techs are looking for more than just vehicles.
10) While SONAR can, in certain situations, pick up the sounds of low flying planes (around 80ft above the surface of the water), it is not reliable enough to confirm that the sub is not being monitored by a spy plane.
11) The author claims that the symptoms of Vampirism include a fever high enough to cause delusions. The signs of this are: flushed skin, degradation of muscular control, lethargy, daze, inability to visually focus, chills (feeling of being cold), and *TOTAL LACK OF SWEAT*. What the book describes is the exact opposite, meaning these fledgling vampires are suffering from severe hypothermia.
12) If these vampires really are suffering from a dangerously high fever, it would take longer than 24 hours for one to freeze solid. Since the body in this book froze solid in a couple hours, that implies that the vampires have a severely LOW body temperature.
13) Doc removed this body from the freezer, where it’s supposed to be stored by Naval instruction, and moved it to an unrefrigerated, active work center. they seem to think that the body won’t now rot.
14) Numerous crew members have now witnessed an officer maliciously harassing an enlisted man, but no-one reports this blatant misconduct. There seems to be no form of command structure designed to protect the enlisted from being abused by the officers.
15) The beds are called “Racks”. Not bunks. Just call them racks, and stop swapping between terms.
16) The entire sub was searched, and this one guy was just chilling in his rack? The rack is the first place anyone searches for someone.
17) SONAR picks up a contact, reports it to the captain, and fails to give a contact classification. STS1 basically steps out of SONAR and says “Guess what I found?”
18) Whiskey Tango Foxtrot is that radio operator doing assuming a watch station WITHOUT confirming that the radio was operational!?
