So long SAW?

Defense News (www.defensenews.com) is running a series of highlights on the recent Modern Day Marine 2009 expo. There is so much to read about this expo! One thing that caught my attention was the following:

So long SAW?

I was totally unaware of the Marine Corps intention of replacing the SAW by the IAR.

DCS Black Shark: Nap of the Earth (NoE) Flying with the Radar-Altitude-Hold Flight Mode

The best way to deal with enemy radar-guided missiles while piloting the Ka-50 featured in DCS Black Shark is not to get shot at. Nap of the earth (NoE) flying reduces the chances of an enemy radar getting a lock at the Ka-50. NoE flying is very exhilarating, but requires a lot of concentration. This blog entry is about the use of the radar-altitude-hold flight mode to make that NoE flying a bit less stressful.

As soon as you get the Ka-50 flying straight and level (and low), hit the altitude hold button in the autopilot panel (see image below). Make sure that the mode of holding altitude is based on radar and not on barometric readings.

The altitude hold button on the autopilot control panel and the altitude source switch. Click the image to expand it.

The upper panel lights up with an easy-to-see reminder of what you have switched on. Click on the image to expand it.

Once the altitude hold flight mode has been engaged and you are flying straight, level and low hit the collective brake lever ([F] in the keyboard) to set your current altitude as the desired altitude. Your Ka-50 will now fly at the altitude you just selected. Your airspeed can be adjusted by slightly pushing (increase airspeed) and pulling (decrease airspeed) the cyclic. I repeat "slightly": if you move the nose of the Ka-50 more than 5 degrees up or down from level, your Ka-50 will climb or sink. In this screenshot I'm making 200 km/h at 7 meters of altitude without any effort. Click the image to expand.

The time has come to reduce the airspeed: pull the cyclic, but don't let the nose to go up more than 5 degrees or you will climb. Note the aircraft datum in the HUD display: nose is no more than 5 degrees up. In this example, I reduced the airspeed from 200 to ~120 km/h without changing my altitude too much (just one meter up!). Click the image to expand it.

Nose up to stop the Ka-50. Note the low altitude. Click the image to expand it.

Surprise! The radar-altitude-hold flight mode will automatically fly your Ka-50 over hills of moderate slopes. Click the image to expand it.

"Warrior's Rage: The Great Tank Battle of 73 Easting" Trickling into Bookstores

This book is trickling down to the shelves of the biggest bookstores in the Washington DC area. It was about time (it was available at Amazon since the beginning of September)!

I got my copy this morning and browsed it briefly. From what I could read, it looks like a great tactical analysis of the battle, with frequent references to the operational situation. Right at the introduction the author bashes the US Army top brass quite a lot.

I thought the book was going to be a bit more thick. This is a picture of the book on my desk.

Looks like a great read for fans of Steel Beasts ProPE.

More details later.

DCS Black Shark: Where did my target go?

Flying an attack helicopter in combat is a very demanding task. Keeping track on the targets, the threats, communications, weapon systems and flying the damn thing at the same time is the pinnacle of multitasking. Ed Macy put it very eloquently in his book "Apache": "... taking an Apache into battle is like playing an Xbox, a Playstation, and chess grand master simultaneously-while riding Disney World's biggest roller coaster ..." The information overload used to kick me hard when I couldn't find enemy units or landmarks I've seen in the Shkval just before performing hard evasive maneuvers. I reckon that probably the main cause for this is the shock of the near-(virtual) death experience (I tend to kill myself just maneuvering out of a missile's path). But I digress.

The I-251 "Shkval" electro-optical targeting system offers a great way to find back that enemy unit, landmark or general terrain area I have just been watching before maneuvering the Black Shark. The trick is locking the Shkval onto that point of interest before losing sight of it.

Locked into a multistory building. Please note the appearance of the building in front of the one I've locked. Click for an expanded view.

Now performing a 360 degrees turn while descending. I've lost sight of the building and off course the lock on it. Click for an expanded view.


Turn and descent complete. Now looking at the general area again from a lower altitude, the Shkval is in ground stabilized mode pointing just a few dozen meters ahead of the previous lock (do you recognize the building that was in front of my previous lock?). Click for an expanded view.

Everytime you lock onto something, the Shkval stores the target's angular coordinates and range into it's memory. I suppose this allows the targeting system to point itself back into the area you have locked into. I'm sure that there has to be a limit for how long in time or how far spatially you can be from the original lock-on in order to get the targeting system keeping the data in its memory. But as you can see I descended a lot from my original lock-on position, turned 360 degrees and still the targeting system was ground-stabilized fairly close to the original lock-on.

"The Defense of Jisr Al Doreaa", A New Classic in COIN

Have you guys read "The Defense of Duffer's Drift", the classic book on small unit tactics written by the British soldier and military thinker Major General Sir Earnest D. Swinton? "The Defense of Duffer's Drift" is centered on the defense of a river crossing by a young officer in charge of a platoon of British light infantry during the Boer War. This officer has a series of dreams, each one starting at the planning of the defense, going through the unsuccessful attempts to defend the drift and ending in a series of lessons learned that he applies in the next dream. In the final dream, the young officer finally succeeds. There were at least one other book with the same format of "plan-execute-improve" cycle of dreams: "The Defense of Hill 781", by Robert McDonough (if you are playing Steel Beasts, this one is a must).

"The Defense of Jisr Al Doreaa" is written in the same format, but the defense is now of a combat outpost in modern Iraq. The young officer belongs to the US Army and goes through six dreams in which he and his troops fight insurgents in the small town of Jisr Al Doreaa. The officer faces challenges that will push him to polish his knowledge of tactics he learnt for conventional wars (security, sector defense, correct assesment of fields of fire, etc) and learn new the new tactics required for fighting an insurgency (patrols, counter-ambushes, counter-sniper tactics, how to move through the "human terrain", etc).

Learning tactics from after action reports or other type of combat narrative is always easier and more enjoyable when there is an explanation of why and how the tactical decisions were made. That is exactly what makes "The Defense of Jisr Al Doreaa" such a wonderful book.

The book is short enough to be read in one sitting and is formatted in a way that would fit in a slightly oversized pocket. Perfect for reading during that last leg of the airlift and sized to fit into any pocket of the combat fatigues. Don't get fooled by the lenght or size of this book: it packs a lot of knowledge.

As a bonus, a copy of "The Defense of Duffer's Drift" is included at the end.

Beautiful map artwork in ProSim's latest free wargame

As you know, ProSim (partnering with their publisher Shrapnel Games and the Armchair General magazine) has released a free war game with two scenarios based on the battle at the Tallil Airbase during Operation Iraqi Freedom.

The maps artwork in ProSim games keeps getting better and better. In the screenshot below you can see An-Nasiriyah (the town north of the Euphrates river). An-Nasiriyah ... any chance we get to play some Marines scenario in the future?

Strike mission right into a SAM nest

The flight sim: "Wings over Vietnam"
The mission: Strike a North Vietnamese airbase
The machine: F4J Phantom II

I've chosen a low flying approach into the target zone. That little box on the dashboard is a RWR/threat indicator. The North Vietnamese are painting us with all the have. In the background, two SA-2 SAMs have been launched in quick sequence. Click on the image to expand.

After striking the airbase with free-fall bombs, I egress the target zone with a steep climb, jinking and watching for SAMs. Burning fuel tanks can be seen in the airbase. Click the image to expand.

RTB, finally. Fast but with the throttle just short of afterburners. The North Vietnamese will send some interceptors sooner than later. Click on the image to expand.

The angle of attack(AoA, red square) indicator of the "Double Ugly". It really shows that this aircraft was designed for the US Navy (by that time Navy aviators were trained to land at a fixed AoA rather than at a fixed airspeed). Click in the image to expand.

This flight simulator is a strange thing. It seems to capture the feeling of fighting over Vietnam during the 60-70's, but so many simplifications are starting to drain the fun.

Bellus interruptus, the ugly side of PBEM in Combat Mission Shock Force British Forces

As you know, I have been PBEM a Combat Mission Shock Force British Forces scenario with my friend Olav.

This screenshot from my PBEM battle with Olav. I'm commanding the British forces and we are advancing very slowly to secure a start position for the assault on the first objective. Click the image to expand it.

Sixty turns or so into the battle, my computer could not handle the scenario anymore and we had to call it a day. There were 60 turns left in this scenario. What a pity. This is not the first time that this happens to me. Other big scenarios have crashed on me in turn-based solo matches.

This section is patrolling the groves, making way for the armor. Click the image to expand it.

It was a great battle and I'm going to post more about it in the following days.

Cheers,

P/S: Olav, can you push the "Cease Fire" button? I would like to see the body count. I am affraid there are lots of virtual families that will need letters.

Books recently published or to be published soon ...

... that may be of interest for the simulation fans who visit this blog.
This one is already out in the UK. Let's hope that they publish it in the US sooner than later because I read only good things about this book. As you remember, Ed Macy already had authored Apache. If you are into DCS Black Shark, like this book you will (Yoda's advice :) ).

This other book was published by the Naval Institute Press, but will be available in US stores later in September. There is no shortage of books and reports about the Battle of 73 Easting, but Douglas Mc Gregor is a top-notch soldier, writer and thinker. Looking forward to feed my already big Steel Beasts ProPE passion with this book.

DCS Black Shark: "A Stick and Rudder Man's Guide" at SimHQ

Frank "Dart" Giger (SimHQ Aviation and Air Combat co-Editor) has written a wonderful article on how tackle the complex task of flying the Black Shark.

Mr. Giger is a great writer and a straight forward thinker. His previous article on DRM schemes in games was brilliant.

As I recently started to fly "Wings over Vietnam", with its extremely simplified avionics and target acquisition systems, I found the following paragraph spot on (bold is mine):

I dislike “switch simulations” with a passion. Nothing sucks the joy from my soul quite like the word procedure in relationship to the operation of flight simulation, and referring to an aircraft as a platform is the height of insult in my book. It’s not the technical brilliance of the band and the craftsmanship of the floor that that excites me near as much as the woman I’m dancing with, after all — and it’s the only reason I’m there, to be honest.
