And this link even has a third video with similar footage.

In Google maps:
The area south of this defense line seems to be something like gardeners plots.
On a larger scale:
Red = known positions
Dotted blue = approximate Ukrainian airport area
Blue arrow = advancing Ukrainian army
It shows that the defense line they have build is FACING the airport, but NOT the advancing Ukrainian army.
Probably they will have built some more defenses like this too:
But even then... basically they are out in the open. They have NO protection against artillery. This is suicide for them... Garden houses won't give a lot of shelter either.
Btln "#Vostok" has plenty bullets but almost none mines, mortars, ATGMs/MPADSs, 7 APC-BRDM, most broken, 5 AA guns w limited ammo.
