The tech itself isn’t secret, both sides use it. With Russia being ahead apparently. From the article:

A video from a Russian military Telegram channel from last month demonstrates their ominous capability. A fibre optic drone, the nose of the yellow cylinder housing the coil clearly visible, flies with precision a few centimetres from the ground, to strike a Ukrainian howitzer concealed in a barn, a location clearly previously considered safe.

But as Fedorenko acknowledges, it is Russia that, at least for now, “is well ahead of us” – largely because Moscow has had greater access to fibre optic cabling, with Ukraine scrambling to catch up.

Hallo

If could be so kind and DM it to me as well? I’d appreciate it.

I’d appreciate some feedback on what I’m looking to do.
I’m wanting to follow the FUTO guide, but I don’t want to build a router, to save on some money for now.
So I’m planning on buying a Mikrotik MT RB750Gr3 and putting OpenWrt on it, then using my current TP-Link Archer C6 as a wireless access point. (will buy a dedicated AP in the future).
One thing I wonder is, if there is a Mikrotik model that would be better?
