At present, ISIS is predominantly the single armed group comprising of about 7,000 combat troops which is militarily active in Iraq to achieve its ends of establishing a Sunni state carved out from Iraq and Syria. . Formed on 8 April 2013, after publically disobeying its mentors of Al-Qaeda by Baghdadi on ideological issues, ISIS has an ambitious plan to establish a caliphate that is an Islamic state, led by a supreme religious and political leader known as a caliph and to be located in western Iraq and north-eastern Syria.
ISIS is opposing the American supported the empowerment of the Shia majority in Iraq. ISIS on its ongoing assaults on Syria and Iraq, has also been joined by jihadis of other nationalities, including Saudi Arabia and the Arab World, Germany, France, USA and the Caucasus. While ISIS is getting monetary support from some Saudis and some sympathiesers of the Arab world, of late, it has started selling crude oil to smugglers and successfully created its own kitty to fight against Iraq and Syria. This crude oil is being extracted mainly from the captured oil fields located at northern city of Mosul and Baiji in Iraq and Syria's largest oil field, al-Omar and being refined in Kurdistan region. Since oil is an easiest mean to collect revenue, the ISIS is trying its hard to get control of maximum oil fields in its on goring armed assaults in Iraq and Syria to achieve its goal of establishing an Islamic State in the region. According to some estimates ISIS is extracting about $1 million worth of oil per day . The rise of ISIS is being considered as fall of Al-Qaeda in Iraq.
Meanwhile, Jamat Ansar Al-Islam(JAI), an anti-Shia militant group in Iraq projects itself as a protector of the country's Sunnis. Active since 2007 JAI considers itself an arch rival of ISIS and mainly based in Nineveh (particularly Mosul), Kirkuk and Salahuddin provinces. Despite having ideological similarities with ISIS it does not have congenial consanguinity with the latter. JAI claims to have meaningful presence and carries anti regime and Shia operations in Ninawa,Mosul,Salah ad-Din and Diyala provinces and even in the Baghdad area. However, in the recent past, JAI's operations were overshadowed by ISIS's successful military onslaughts in the country but JAI refused to accept hegemony of ISIS in its successful operations in Syria and Iraq. JAI opposes ISIS considering itself a 'state' rather than a Sunni group against Shias. This has been resulting into frequent clashes between armed jihadis of JAI and ISIS primarily in the Kirkuk and Mosul areas.JAI even claims that during last nine months ISIS had killed around 40 members of JAI without any serious provocations.

Abd al Hakim al-Nuaimi, a prominent leader of the JAM has confessed of having differences and armed clashes with ISIS inside bordering areas of Syria. JAM also maintains special relationship with JAI as a counter to ISIS,
Another anti Shia regime and Sunny jihadi group in Iraq is Jaysh Rijal al Tariqa al Naqshbanhi (JRTN). JRTN, the second largest insurgent grouping in Iraq after ISIS is headed by Izzat Ibrahim al-Douri, who was Saddam's right-hand man. The group believes and propagates the Naqshbandi 0rder, the spiritual order of Sunni Islam Sufism. JRTN is Iraq's main Ba'athist insurgent group, which actively opposed the presences of American forces in the Iraq after assassination of Saddam Hussain. JRTN has also its political activist wing namely, Intifada Ahrar al-Iraq. JRTN is considered to be mix of Islamic and pan-Arab nationalistic ideas operating mainly in Kirkuk and other parts of northern Iraq and basically follows the guerrilla tactics. Although JRTN has ideological differences with ISIS , it is not engaged in any armed conflict with the latter.JRTN a front Baathists, which is unified under the "General Military Council for Iraq's Revolutionaries" (GMC).

However, after the US withdrawal at the end of 2011, IAI was formally demolished and it turned towards political activism.

In early this year, IAI once again resorted to the armed activities against the Iraqi regime and mainly remained active in Diyala and Salahuddin provinces. The IAI is engaged in achieving its objectives by means of political activism as well as the continued use of violence in Iraq.
Jaysh al-Izza wa al-Karama also known as Army of Pride and Dignity (ADP) came into existence in last of year 2013 at Anbar, Iraq, under the leadership of Dr. Mohammed Naser al-Abdallah.
