Very Factual 10
29 April 2019 | by dncorpSee all my reviews

A very long time ago before my U.S. Military Career Field was permanently changed to U.S. Military Joint Services Special Warfare my U.S. Military Career Field was Nuclear (Weapons) Physics and Physiology. What I found out is how most Nations just "tolerate" Nuclear Physicists, like those that created the First U.S. Atomic Bombs, as minimal pay and almost kept like prisoners and always suspected of leaking secrets as to why actually they released the secrets of the U.S. Atomic Bombs to the U.S.S.R. and not the so called Jewish Spies Julius and Ethel Rosenberg. Being kept nearly poor and had to maintain the U.S. Atomic Bomb Secrets, could not get a Job that might reveal anything like Physics Teacher or Professor, and no money from Patents, not surprised that they sold Secrets to the U.S.S.R. and Chinese.

Without getting into Classified Nuclear Weapons Design Information, having previously dealt with U.S. Small Atomic Demolition Munitions (S.A.D.A.M.s), yes you could design a Portable Nuclear Weapon, just not the complex design depicted. As about a 10 Kilo Tons Yield Portable Nuclear Weapon, the Atomic Bomb dropped on Hiroshima was 15 Kilo Tons Yield, the Atomic Bomb dropped on Nagasaki had a 21 Kilo Tons Yield, so based on my previous training, a 10 Kilo Ton Yield would be more than enough to flatten City of Hong Kong (must be detonated at a certain location for maximum effect).

Good guys do not always win, like in the Hollywood movies, as to why those expecting the Good Guys to win like in the Hollywood Movies rated this low below 6 Stars.

Entertainment 10, lots of action.

Fight scenes very accurate except good guys getting shot multiple times and not immediately dying, Rating 8.

Accuracy ?

Cameras do not work, some electronics do not work, close to a nuclear weapon, as the unshielded nuclear weapon emits radiation and a broad spectrum of frequencies.

Clear plastic rain suits are not used to protect against Radiation, must have metallic coating of a very dense metal.
