Notable that the characters, who for the most part, are age 40+, all are in top physical condition; probably able to leap tall buildings. Here is a challenge I'll set for you - if you happen to come across a character who is not in tip-top shape - please let me know.
This thriller dashes smoothly along - yet I stumble when an acronym, of which there are many, pops up. Here is a sample; and another challenge - see how many you know without checking your smartphone. MSS, HUMINT, MWTC, DARPA, ONERING, GEO, HRT, ACLU, SCUD, JSOC, NH90, UOE, Type 67, M18, XM25, AH-6, SIGINT, IMINT, SAP, DSS, RSO, MRAP QRF, UAV, QRF, Hind Mi-24, LEGION, CNPC, DEFSMAC, AMD, NGA, CRITIC, SOO, NSOC, NOAA, NSOC, PLA, ch-53f, FLIR, M79, CH-53E, HLZ, NEO, GS14, EOD, ViCAP, That's about it; the others you readily know - CEO, CIA, FBI, USA, SUV, NIA, DoD, DC, IQ, GPS, ATV, SEAL, UN, USAID, ER,DNA, PD, IED, ETA, UAV, NSA.
When I was stationed in Germany, in security, we had a daily weapon issue, which we signed going on and of shift, of either a 45 or M1 - never both. In this thriller these guys get all they can carry - PP2000, Kimber .45, Heckler & Koch PSG-1 MP5, Type 5 submachine gun, AK47, H&K MB5SD-N KA-BAR,COLT M911, M4, Sig-SAUER: like they were on a shopping spree at Walmart.
Both sides had their detailed plans of assault : usually they had to switch to Plan -B - that made it more of a thriller. Some people got killed, usually in interesting disgusting ways - made for a better story: the swim in the Nile is a gem..
Towards the end, the team meets the President, their Commander-in-Chief - a former Air Force officer who'd flown A-10 missions during Desert Storm. (compare that with a clueless 4x draft dodger commander).
The final chapter brings back a character that I had completely forgot about.
Oh, Matthew, from your book cover photo I notice you've dropped your buzz cut standards and also acquired civilian casual; thanx for another thrilling thriller.
