...procurement programs and the MLRS artillery rocket system in the late 1970's-to-early 1980's.
The post 1973 Arab Israeli War US Army understood the idea of "the logistical costs of a stowed kill." 2/
The US Army kept the 105mm on the M1 in production so long because the depleted uranium (DU) 105mm "Long Rod" APFSDS could kill a early T-72 and you could carry 55 rounds versus 40 rounds for a 120mm gun firing a tungsten APDS or early DU APFSDS round.
3/
A single "Army 1985" 27 launcher battalion of MLRS with its boxed rocket pods could deliver the same volume of cluster munitions fire as sixteen 12 tube 203mm howitzer battalions.
The infographic below shows the manpower/shipping advantages the US Army was looking at.
4/
To date, no one has done a real logistical, cost effectiveness & weapon effect/lethality numerical evaluation of FPV drones versus conventional weapons systems.
This thread will address this by starting with this Bradley/Abrams/GMLRS in Iraq video.
5/
In order to get the weapon effect of the 25mm chain gun, 120mm cannon and GMLRS rocket you just saw in Iraq, a 35-ton, 70 ton or 17-ton vehicle respectively have to be moved by sea halfway across the planet to Iraq.
6/
Now compare all those US Army weapons to the impact of this Mammoth FPV drone with a 4 kg warhead.
It is competitive in weapon effect. And in terms of cost and logistics to move it to target, it's superior.
Drones are 'disintermediated' from classic military weapons platforms. 7/
Heck, you can move dozens of FPV on an airline seat.
Meanwhile those M1/M2/HIMARS loaded merchant ships will have to deal with a gauntlet of Houthi/Iranian anti-ship ballistic missiles (ASBM), anti-ship cruise missiles (ASCM) or Boat-Drones to get there.
8/
Please also note, each 14 of such vehicles there will be one M1070 HET, and either a M88 Hercules tracked ARV or one HEMTT wrecker.
In addition to that, there will be a huge logistical tail of fuelers and ammo trucks running the same Houthi missile/boat-drone gauntlet.
9/
Now compare all those US Army weapons to the impact of this Mammoth FPV drone with a 4 kg warhead.
It is competitive in weapon effect, and in terms of precision, cost and logistics to move it to target, it's far superior.
10/
By my count there are at least 4 or 5 overlapping revolutions in military affairs that are downstream from FPV drones. off the top of my head:
That 0.28 square km versus 78.53 square km, a 54.46 to 1 FPV area denial engagement advantage.
16/
The worse case for FPV drones versus 5.56mm kills are as follows
11.29 to 1 FPV logistical effectiveness advantage. 4.2 to 1 FPV cost effectiveness advantage.
54.46 to 1 FPV engagement envelope advantage.
Cumulatively, that is a 70 to 1 advantage for FPV drones versus 5.56mm rifles.
17/
When you look at a Bradley's 25mm round's 2.2 km max range and Tow Missile 4.5 km max range compared to 5 km of a 1st Gen FPV, you have to take into account the concept of dead ground.
FPV can penetrate cover and overfly obstacles to the back side of hills by maneuver. While the Bradley's ballistic shells and line-of-sight missile cannot.
There is no such thing as cover or dead ground for infantry to hide from FPV's.
18/
For comparison:
1st Gen. FPV Drone = 78,539,816 sq meters & close to 100% of coverage of targets
25mm = (π)2.2 km^2 = 15,205,308.44 sq meters at ~50% coverage 7.6 Sq km
Tow Missile = (π)4.5 km^2 = 63,617,251.23 sq meters at ~50% coverage 32.1 Sq km 19/
Nor do you need big centralized fire direction centers like ballistic artillery.
Small FPV drones can use "ground loiter" near the front lines, communicated via antennas with long cables to where the FPV operators are located under cover & concealment, to do the Artillery fire support role faster.
The logistical facts are that the FM-MAG machine gun, the 60 mm & 81mm mortars, LAWS, Javelins, any infantry crew served weapon you care to name are all going to be most to fully replaced with drones and drone operators, because of the logistical leverage drones represent on the battlefield.
23/
In Vietnam, Korea, and WWII it took between 50,000 and 100,000 rifle bullets to inflict a casualty, and that casualty was almost by definition at a maximum depth of 300m or so.
That’s between $5000 and $10000 at 0.10 per round against targets within a range of 300m.
Let’s say $5000 for argument’s sake. Let’s also say a FPV costs $500, and use Ukrainian statements that only 10% of missions succeed.
24/
Again we arrive at $5000 per successful hit HOWEVER, they’re hitting out to roughly 5KM, not sub 300M.
If we assume that the effective range is a hemisphere facing the enemy, the measure of the effectiveness of the system is the area of that hemisphere less, dead ground.
So a FPV drone is about the same cost per hit, but will do it over 278 times the amount of ground compared to rifle fire.
It will also deal with a variety of targets that rifle fire can’t. It is capable of killing light vehicles (even MBTs depending on the warhead), and capable of inflicting multiple casualties per hit.
Ten drones at around 15 pounds per drone/warhead is 150 pounds of logistical burden.
Fifty 1000-round cases of ammo at 30 pounds per case is 1500 pounds of logistical burden.
26/
5km ranged FPV have a 70 to 1 combat advantage over M-16's and 40 or 50 to one over every infantry carried crew served weapon imaginable when logistics, cost effectiveness and engagement envelope are looked at holistically.
27/
Looking at these factors and trying to consider range (access to more targets) capability (effectiveness against more types of targets) and area effect (more targets serviced per hit) FPV drones are probably TWO or THREE orders of magnitude more cost-effective than rifle-fire at producing casualties.
It pays to use FPV's against anything and everything, so long as they can be supplied in quantity.
28/
Tanks and self propelled artillery inherently require enormous amounts of fuel and ammo.
The fuel & ammo delivery vehicles cannot operate in drone-infested areas.
Much of the direct firepower tanks and indirect tube artillery deliver can be delivered by drones.
29/
The artillery heavy, but more analytically inclined, ROK Army is seriously thinking about "Crossing the Drone Logistical Cost Effectiveness Rubicon" versus ballistic shells by converting its battalion mortars into drone units.
I suspect another reason ROK is looking hard at drones is they are 'disintermediated' from any existing military combat platform to deliver their 100% precision guided firepower.
I don't need a Javelin missile launcher, or AFVs to deliver 25mm, 120mm or 155mm tube firepower.
31/
I just need the drones and a commercial off the shelf controllers that thousands of children and teenagers are growing up with.
Where the Small/Cheap/Many beats the Big/Expensive/Few paradigm is that societies with a large drone using nerd/geek middle class can deliver... 32/
...lots of 'military weapons systems capable' manpower.
Drone controllers are universal.
The skills sets required for M2's, M1A2, AH-64's or F-35's are hard to gain, expensive to maintain, and those weapons systems are simply much harder to move on a theater/global scale.
33/
The issue of the disadvantage of ballistic weapon dead ground versus Drone's powered advantage is the traditional crewed close air support orbiting a battlefield with rockets and 500lb bombs, but smaller & cheaper.
Drones, with 1.5 kg precision guided warheads that hit between 20% & 70% of the time, have a "granularity" due to their three to four figure dollar cost that can effectively engage single infantrymen in a trench.
Drones of the FPV class are getting better & longer ranged at an impressive rate.
10-inch FOV frame FPV drones with cheap Chinese thermal sensors reach 16 km for $1,500.
Ukraine's lawn mower engine powered FPV drones are reaching 35 km and likely cost around ~$4,500 each.
36/
This SPC chart I did of Russian Army artillery tube losses in December 2023 is, I think, the first statistical look at FPV drones' real battlefield impact in Ukraine.
Between Dec 9th & Dec 16th 2023 there was some combination of 155mm shell shortages, a lot of bad weather, Russian drone jamming and/or Russian tubes & MLRS being pulled out of Ukrainian FPV drone & artillery range.
[When I computed the lower limit for Russian artillery tube losses, it was a nonsensical -15 point something. So I simply put in the value of Zero.]
37/
A general lack of FPV drones in Dec 2023 would have put the Ukrainians at the May 2022 situation ala Siever Donetsk.
This is an defense analyst comment on the SPC chart (above) that I shared in mid-January 2024:
38/
Not long after that, made the following observation on the patterns of casualties from FPV and other drones in the Russo-Ukrainian War.
Now imagine moving an M109A6 Paladin and its wrecker/fuel truck/ammo truck logistical slice by ship 1/2 way around the world, fighting past Houthi missiles, only to see thirty $4.5K lawn mower engine powered FPV drones sweep the lot and do most of the artillery mission besides.
40/
It is thinking through the strategic logistical realities of the lowered barriers to entry for drone combat power that the bottom drops out for all the current US Military power projection organizations, platforms and missile paradigms.
We are seeing $50K to $100K drones operated by a technologically unsophisticated Houthi culture now demonstrating that new reality in the Red Sea
Burke class warships are shooting their VLS tubes dry of $1.2M SM-2 or $4.3M SM-6 missile that can't currently be reloaded
42/
...outside of a port more than 1,500km from Yemen, AKA the extreme range of the Houthi/Iranian assault drones.
There needs to be a new class of DD tenders for the US Navy capable of high speed underway replenishment of missiles to prevent Burke class block obsolescence. 43/
This new class of DD Tenders will have to be heavily armed combatants in their own right, with Navy crews and a lot of automation, to survive in the peer to peer drone/ASBM/ASCM envelope to replenish carrier battle groups.
43/
Until the US Navy gets these self-defending "combat auxiliaries," the ability of the USA to project power is now like Great Britain in the age of sails.
Given the reality of massed drones & ASBM's, we have returned to the Nelsonian age of "A Ship's a Fool to Fight a Fort" 44/
...because the US cannot afford to combat drones with its current missile technology.
Plus, franky, the post-Cold War US Military staff lacks the analytical rigor to recognize the logistical/cost effectiveness issues involved.

What killed Imperial Japanese soldiers in WW2 "without a mark" inside bunkers was carbon monoxide poisoning, not a lack of O2.
Once you get enough CO in the lungs on the O2 chemical bonds.
No further O2 can get into the bloodstream and you suffocate.
2/
I ran across that fact in a trip report of a US Army Chemical Warfare Service (CWS) medical doctor sent to Leyte to take blood samples from IJA corpses that died from flame weapons.
It didn't work out and the CWS used goats in bunkers hit with flamethrower weapons to get the CO poisoning medical data.
Any trench w/o overhead cover and any passage or firing slit that is big enough to shoot a crew served heavy weapon or vehicle out of is also big enough for a FPV drone spewing thermite to fly into.
2/
Every field fortification manual ever written by every military in the world is obsolete and will have to be re-written with an eye to placing curtains, nets or wire screens across firing slits and doors to keep out small drones.
The "missile" impacts have the classic artillery rocket impact ellipse with strikes being on the line of flight axis having more dispersal (long/short) that left or right of it.
One of the spaces @secretsqrl123 had with @RyanO_ChosenCoy present. He made clear Ukrainian FPV drones based on Hollywood camera multi-copters have a 50 km one way range.
The other issue is the disintermediation of drones from platforms. 1/
"Disintermediation" means any shipping container or flat space on a vessel/vehicle works as a launcher.
A ISO container with 126 drones can be stacked on a 24 X 24 top level of a Chinese MGX-24 container ship and lob 72,576 drones in a simultaneous wave 50 km or more.
2/
Another thing that works are simple racks in cargo aircraft, helicopters or boats.
The Russians are using simple racks in the Mi-8 to hold FPV drones in large numbers to engage Ukrainian boat drones or special forces craft with MANPADS or FPV's.
Missiles are structurally strong nose to tail because, rocket acceleration. Side to side missile structure is as weak/light as possible for performance reasons.
Railway gondola cars moving missiles like this rattles them side to side like beans in a maraca.😱
It takes 40 hours for RuAF casualties to reach medical care equivalent to a battalion aid station.
The odds are RuAF field hospitals will not be able to control the infections that thermite burns generate, because they don't evacuate quickly enough. 2/
