I've enjoyed Conroy's work in the past. Fast-paced, not too deep but goods stories, ideal for something I would consider light reading. However, this effort has even more of what makes me apprehensive when picking up a new title by him - lack of technical knowledge.
The author should really consider having someone with military experience proofread his writing for mistakes and misapprehensions. They crop up frequently, and act as speedbumps to the flow of the narrative to anyone with military and historical knowledge - his target audience.
Examples - He refers to the M-2 Browning as an "ancient machine gun." While the M-2 is a WW1 design (as the M1919), it has been in continuous production in its current form since 1933. There is no way to look at an M-2 and tell when it was manufactured, and the context clues in the narrative point to the specific weapon not being old, but the design being old and out of date.
In another part of the text, the Cuban Air Force attack the base with multiple jet fighters. In DEC 1962. There is no narrative explanation as to how the Cuban Air Force got possession of state of the art Soviet jets two months after the Cuban Missile Crisis. At the time, the Cuban Air Force was composed of Bautista remnants, mostly WW2 vintage piston engine aircraft, with an amazing lack of spare parts.
Also, one of the Marine commanders wishes for TOW missiles, which were not fielded until 1970, during an attack in 1962. Further, he wants to be able to fire them from inside the bunker. Wire-guided missiles of the late 1950s were huge, and were emplaced, not moved about while under attack to an alternate bunker. Likewise, the BTR-60, which the author states was used in the 1962 attack, was not sen in public by non-Soviets until 1961, so how likely is it that Cubans would have any of their own in the field?
There is no 24mm Oerlikon anti-aircraft gun. There's a 20mm, which has been standard from 1937 to today, and manufactured under license in several countries.
The C-54 did not drop paratroops. One experimental version with two troop doors may have been produced, but the aircraft was used for cargo, not airborne operations. The C-1119 was still being used for paratrooper training, and the new(ish) C-130 was being used in increasing numbers by 1962.
It's a shame that authors who can spin a good tale cannot expend the effort to get the small details correct, for it is in those details that the suspension of disbelief lies. In this aspect of storytelling, Conroy fails for this volume.
