 As the battle for Tripoli progresses, Turkey increased its military support to the pro-GNA forces - at first the Turkish support to the GNA was limited to political support, sending military equipment (on May 18, 2019., Turkey reportedly delivered from the Turkish port of Samsun to Tripoli, via a Moldavian-flagged ship "Amazon", more than 20 BMC Kirpi and BMC Vuran 4x4 MRAP vehicles, as well as two Ground control stations/GCS for the Bayraktar TB2 UCAVs and large quantity of MANPADs, ATGMs and Bulgarian-made light arms), as well as sending military advisors to train pro-GNA soldiers.But starting from June 2019, the Turkish military reportedly started to fly UCAVs in direct support to the pro-GNA forces, scouting and bombing pro-LNA positions around the city of Tripoli, and this increased Turkish military support reportedly helped the pro-GNA forces to stop the pro-LNA military advance on the city of Tripoli.The Turkish military presence on the frontlines around the city of Tripoli soon became obvious - on June 1, 2019., according to pro-LNA forces, its anti-aircraft defences shot down a Turkish-made UCAV when it bombed pro-LNA positions around the town of Gharyan.
