US measure to list Islamic Revolution Guards Corps (IRGC) as a terrorist entity promoted the unity among Iran's armed forces, a senior Iranian Army commander said.

The Iranian Army and the IRGC are united to defend the country and the Islamic establishment against enemies, Commander of the Iranian Army Ground Force Brigadier General Kiomars Heidari added.

He made the remarks in an exclusive interview with the Islamic Republic News Agency (IRNA) on Friday.

IRGC's hand will be in the hands of Iranian Army, people and Supreme Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei till the end of global arrogance, the commander stressed.

He said that US President Donald Trump's unwise decision undermined the security of US forces across the world.

The United States officially designated Iran’s IRGC as a foreign terrorist organization, according to a notice published in the US Federal Register on April, Reuters reported. 

US President Donald Trump said afterwards he would make the symbolic, but unprecedented move which was immediately condemned by Iran. Majority of politicians from all sides of the Iranian political spectrum rallied in support of the IRGC in a bid to show their support. Also, the Iranian lawmakers, wearing the IRGC’s olive green uniforms, attended the parliament on Sunday. 

The Iranian press also opened their front pages with the news and reactions to the move. The reformist Etemad’s page one title read 'I’m a guard' in a clear bipartisan support for the forces. 

The IRGC expressed its gratitude for the show of support, promising 'a reciprocal response to the enemies, especially the rogue and terrorist-producing government of the US'. 

The latest anti-Iran move of Trump received fierce reactions from the Iranian officials. The country's Foreign Minister Javad Zarif in a letter to President Hassan Rouhani called for a retaliatory move by labeling the United States Central Command (CENTCOM) as a terrorist organization and the US government as a sponsor of terrorism.
