I want to give some insights and thoughts into the fight against the Shahed-136 kamikaze drone.
Let's consider several options for combating it:
The easiest way, it would seem, is radio-electronic interference, but there is a problem:
🧵🧵🧵
For effective jamming of a CRPA-type receiver, several different types of interference are required parties. That is several radio interference stations that target the aircraft from different directions parties. All electronics in Shahed-136 are housed in metal housings.
Radio controlling is not used on the route. Therefore, in theory, countermeasures by electronic means have
low efficiency.
It makes absolutely no sense to use radio jamming against the Shaheds on route to the target.
In the event of suppression of radio interference, the aircraft automatically switches to the inertial system (motion in a straight line) until it leaves the radio interference radius. After which restores the exact
positioning and route.
Strong radio interference of satellite signals can only be effective directly near the likely target (radius up to 2 km).
In addition to air defense means (air defense systems, MANPADS), it is advisable to create a network of highly mobile ones anti-aircraft calculations.
The use of heavy large-caliber machine guns is not a priority - to defeat the Shaheds at the average height of their flights (up to 800 meters) the advantages of large calibers (over 7.62) are not obvious.
At the same time, the capacity of the stores and the opportunity are of the greatest importance installation of night sights and collimators, and mobility
For this role, it is optimal to use various modifications installed on an anti-aircraft machine in the body of a pickup truck
I think the use of sniper rifles is not advisable.

Important point! Calculations should be fixed not only on potential goals but also on Shahed's most likely routes.
At the same time, according to each calculation
a straight section of the path is fixed (field or asphalt road)
So that in case of timely detection of the UAV and determination of its movement vector the specific calculation was forewarned of the likely point of intersection in his area of ​​responsibility by Shahed-136 and had the opportunity to move early and take the necessary position.
The most effective for hitting is the use of tracer cartridges. But it is important to note that even after damage in the sky (gas tank, means controls, electronics) the plane remains dangerous when falling, so for increasing the probability of detonation in the sky.
It is advisable to use armor-piercing incendiary cartridges.
If it is possible to choose a position for defeat in advance, you should pay attention to the fact that
downed UAVs that have not detonated in the sky pose a high danger to civilian houses.
There is no need to hide or disguise - Shahed is not equipped with the means of optical guidance.

Aiming at the UAV Shahed-136 from the mechanical sights of small arms while firing without the use of tracer, cartridges are extremely difficult.
It requires precision to take into account 3 parameters - the distance to the target, the vertical decrease of the trajectory of the bullet on distance, and target bias.

Nevertheless, in the presence of several shooters and the chances of concerted action increase.
If the downed plane did not detonate when it fell, do not approach for at least a few hours - the use of self-destruct timers is possible.

A sharp decrease in the noise level (engine evolutions) is a sign that the aircraft is about to attack purposes!

Hello, my name is Roman, I'm software engineer from Ukraine and I assemble combat FPV drones for 🇺🇦 defenders!

A few months ago, I decided to start this project, because it is one of the most effective ways to help my military friends who are fighting for a free 🇺🇦Ukraine!
🧵
FPV drones are a highly effective weapon, especially today when the Russians are on the offensive.

My drones help repel assault by Russian invaders and destroy their equipment.
Watch video:
1st estroyed enemy mortar and ammunition detonation.
2dn - prevent assault, 4 enemy - 300

My goal is to continue developing high-quality FPV drones for specific unit needs, so I make sure to do test fly and get constant feedback from the military.

We have already made several dozen FPV drones and sent them to the front line. Image

I think everyone understands that russia will not stop at Ukraine and the EU countries will be next. That's true!
In turn, in 2014, everyone thought that Putin would be satisfied with Crimea and that it would be possible to hold talks with him on the sly.

A thread.
1/
Many believed that over time Putin's power would change and that democratic leaders would come after him.
Now we see that these were illusions!
2/
February 20, 2014, is the bloodiest day of events on the Maidan and the date of the beginning of the seizure of Crimea.
In fact, since then, we have been living in a state of war for 10 years.

Did you know that Ukraine has 2 flags?
Blue and yellow🇺🇦, and red with black.
If the yellow-blue flag symbolizes statehood and Ukrainian unity, the red-black flag is the Ukrainian revolutionary flag.
Let me tell you🧵
The history of the red&black flag as a symbol of the struggle for the freedom of Ukraine has existed for a long time.
In Ilya Repin's painting "Cossacks writing a letter to the Turkish Sultan", two poles with folded panels can be seen.
One flag is 🇺🇦, and the second is red-black
What do these colors symbolize?
The black color symbolizes the Ukrainian land, and the red color symbolizes the blood of fighters spilled on it in the struggle for the freedom and independence of Ukraine.

Unbelievably, I reached 20,000 followers.

Thanks to your support and my efforts, we supplied many units and created many projects that helped 🇺🇦Ukraine win faster!

I want to tell you a short story about how I started my activity on Twitter to help my friend in the war.
🧵
I created this account at the beginning of the war, perhaps out of desperation and hoping to find help for my friend Mica and others who went to war.

I was looking for different ways to raise money to collect packages and send them to the front.
I remember pulling my account with several posts and announcing my first fundraising.

When I woke up the following day, I had $924 on PayPal. It was a victory, and I immediately ordered a gas generator. This gave me hope and more motivation to continue my activity here

On Valentine's Day❤️, thousands of defenders today defend us on the front lines.
They are eagerly awaited and loved by their wives, children, and parents!
Thousands of messages with the words "I love you" were sent from the front lines and back to relatives and loved ones.
🧵 Image
Today morning, our 🇺🇦defenders could warm the hearts of those they love. Instead, they send the orks back to the cave to hell with fury and zeal.

They could hear "love" live, but they heard the sounds of gunshots! Image
They could hug and kiss their loved ones. But, they are "embraced" by the frosty wind.

Today they could give flowers and valentines to their loved ones, but instead they give valentines (shell shots) to the Russian occupiers. Image

I would like to comment on a few phrases of Mrs. Gwynne Shotwell about Starlinks and their use with drones and offensive purposes in Ukraine.

Does Starlink work now in 🇺🇦Ukraine, particularly on the front line?
🧵

reuters.com/business/aeros…
First, I want to clear up all this noise about Starlink not working on the front lines.
I checked it. And as proof, Starlink, which is at the front, as you can see, WORKS, and 7 soldiers are attached to it. Image
As for the comment about using Starlink to control a drone
First, I don't know and have yet to hear any proof as well as in the article. If someone stuck Starlink on a drone, the whole internet would buzz about it

This is ineffective and less unrealistic with current conditions Image
