Sh1n (@hey_itsmyturn) reposted a report from Ali Al-Sakani (@Alsakaniali) about a Yemen National Army (YNA) FPV drone strike on Houthi forward positions:

A FPV drone from YNA hit Houthi fighters in their forward positions on the northwestern #Marib front.

The repost quoted an earlier report by Al-Sakani describing a separate strike on the southern Marib front:

Another Houthi military vehicle is taken out in an FPV drone strike on the southern #Marib front.
The YNA appears to be stepping up its use of FPV drones along the frontlines of Marib.
