Along the Russia-Ukraine border, badly stretched Ukrainian forces are struggling to deny Russia a foothold.

The town of Volchanks just three miles inside the border has seen some of the fiercest fighting since Russia

launched its offensive. That's where John Ray of Independent Television News joined

soldiers from Ukraine's 57th Brigade.

These are anxious times for Ukraine.

And especially for the men of the 57th Brigade.

The shooting starts the moment we arrive.

Under the three lines.

It turns out they're hunting a drone that's hunting them.

There's danger from every direction at any time. It's so loud.

They're striking with everything.

They have this right.

Oleg is a new recruit and already an exhausted veteran.

Everything very difficult, very hard.

A lot of rockets, a lot of drones.

This is drones.

It was like a peace, like everything.

Only you here is zzz.

Other what's like rain, like rain.

Have you had any rest?

No.

No.
