Almost 4 weeks into Operation Epic Fury, United States President Donald Trump has claimed that Washington is engaged in negotiations with Tehran – talks that Iran denies are occurring – whereas amassing 1000’s of troops within the Center East.
What started on February 28 as a joint US-Israeli air marketing campaign concentrating on Iran’s navy infrastructure has now, by the ultimate week of March, expanded into the most important deployment of troopers to the area because the Iraq Conflict.

One strike group, affiliated with the plane provider USS Abraham Lincoln, is operationally energetic within the fight zone as of now, with the provider USS Gerald R Ford briefly out of motion for repairs within the Mediterranean.
The air marketing campaign has struck greater than 9,000 targets throughout Iran, together with websites linked to former Supreme Chief Ayatollah Ali Khamenei, Islamic Revolutionary Guard Corps (IRGC) headquarters, ballistic missile amenities, drone manufacturing centres and naval property, in response to US Central Command (CENTCOM).
Greater than 140 Iranian vessels have been broken or destroyed, US officers say. Iran has responded with near-daily missile and drone assaults concentrating on Israel, Gulf Arab states and US navy bases, whereas successfully closing the Strait of Hormuz to most business transport.
The slender waterway, by means of which about 20 p.c of the world’s traded oil passes every day, has develop into the central strategic stress level of the battle.
It’s in opposition to this backdrop that Washington is now reinforcing its floor presence.
US President Trump made no secret of his intentions within the weeks earlier than the primary strikes.
“We’ve an enormous power going in the direction of Iran,” he informed reporters in late January. “We’ve a variety of ships going that route. Simply in case, we have now an enormous flotilla stepping into that route, and we’ll see what occurs.”
After US warplanes struck Kharg Island earlier this month, Trump stated in a Reality Social put up that his forces had “obliterated” navy targets there, warning that the island’s oil infrastructure could possibly be subsequent if Iran didn’t reopen the strait.
On Tuesday, the Pentagon ordered roughly 2,000 troopers from the US Military’s 82nd Airborne Division to start shifting to the Center East, in response to US media experiences.
The deployment provides to 2 Marine Expeditionary Items already en route from reverse sides of the Pacific. US Defence Secretary Pete Hegseth confirmed that CENTCOM had requested the reinforcements to increase operational choices.
US Secretary of State Marco Rubio informed a congressional briefing that the US could have to bodily safe nuclear materials inside Iran. “Individuals are going to must go and get it,” he stated, with out specifying who.
Whereas no floor operation has been authorised but, the convergence of US Marine amphibious forces, elite US Military paratroopers and a division-level command construction marks a big enlargement of US navy choices.
Three forces, one theatre
The reinforcements heading to the Gulf include three distinct formations, every with a distinct origin, route and timeline.
The primary is the Tripoli Amphibious Prepared Group, centred on the America-class assault ship USS Tripoli and the thirty first Marine Expeditionary Unit (MEU).
Ordered out of Sasebo, Japan, on March 13, the group transited the Strait of Malacca and was at Diego Garcia within the British Indian Ocean Territory by March 23. It’s anticipated to enter the CENTCOM space by late March or early April.
The second is the Boxer Amphibious Prepared Group, constructed across the Wasp-class assault ship USS Boxer and the eleventh MEU, primarily based in Southern California within the US.
The group departed San Diego between March 19 and March 20. Masking roughly 22,200km (13,800 miles), it isn’t anticipated to succeed in the fight zone round mid-April on the earliest.
The third is a contingent of about 2,000 troopers from the 82nd Airborne Division’s Instant Response Power, primarily based at Fort Bragg, North Carolina, which was the most recent in line of US navy reinforcements for the area.
Collectively, the 2 Marine teams would provide the US 4,500 Marines and sailors within the area. Mixed with the 82nd Airborne contingent, almost 7,000 extra troops have been deployed because the battle started.
USS Tripoli and the thirty first MEU
The USS Tripoli, an America-class amphibious assault ship, is the bigger of the 2 Marine vessels heading to the Gulf.
Based mostly in Sasebo alongside USS New Orleans, the group varieties a part of the US Navy’s forward-deployed presence within the western Pacific.
The thirty first MEU, in the meantime, includes about 2,200 Marines and sailors, constructed round a bolstered battalion with artillery, amphibious autos and specialised models.
At 261 metres (856 ft) lengthy and weighing 45,000 tonnes, USS Tripoli can function as a light-weight plane provider for F-35B jets whereas concurrently deploying Marines by air and sea.
The thirty first MEU is the Marine Corps’ solely completely forward-deployed expeditionary unit. It has beforehand taken half in Operation Desert Fox in 1998, patrolling off Kuwait throughout the Iraq weapons inspection disaster.
Operation Desert Fox was a four-day US and British bombing marketing campaign in opposition to Iraq in December 1998, ordered by then-US President Invoice Clinton and British Prime Minister Tony Blair.
USS Boxer and the eleventh MEU
The second amphibious group is centred on USS Boxer, a Wasp-class assault ship primarily based in San Diego, California.
The Boxer Amphibious Prepared Group additionally contains USS Comstock and USS Portland, and carries the eleventh MEU, primarily based at Camp Pendleton, in California.
USS Boxer departed San Diego on March 19, and in response to the US authorities, the deployment was accelerated by roughly three weeks from its initially scheduled date.
At a distance of roughly 22,200km (13,800 miles) from the Gulf of Oman, the group is no less than three weeks from the theatre and isn’t anticipated earlier than mid-April.
Like USS Tripoli, USS Boxer can deploy F-35B plane together with helicopters and different help platforms.
The eleventh MEU contains about 2,200 Marines and sailors, alongside roughly 2,000 extra sailors throughout the three ships.
The unit has an intensive fight file within the Gulf. In 1990–91, it shaped a part of an amphibious deception plan that tied down Iraqi forces alongside the Kuwaiti coast.
That marketing campaign adopted Iraq’s invasion of Kuwait and concerned a coalition of greater than 700,000 troops from 35 nations.
In August 2004, the eleventh MEU led operations in Iraq’s Najaf province and remained there till February 2005.
82nd Airborne Division
The 82nd Airborne Division, primarily based at Fort Bragg, serves because the core of the US Military’s XVIII Airborne Corps.
Roughly 2,000 troops from its Instant Response Power have now been ordered to the Center East.
This brigade-sized formation of about 3,000 troopers can deploy anyplace on the planet inside 18 hours.
The 82nd is the Military’s major forced-entry unit, skilled to conduct parachute assaults, seize airfields and safe terrain for follow-on forces. Nonetheless, it deploys with out heavy armour within the preliminary section, limiting its skill to carry territory in opposition to counterattacks.
The division has an extended fight historical past, together with operations in Normandy and the Netherlands throughout World Conflict II.
Extra just lately, it has been deployed to the Gulf Conflict in 1991, Afghanistan in 2001 and Iraq in 2003. It was additionally mobilised to the Center East in January 2020 following the US killing of Qassem Soleimani, a senior IRGC commander.
What might these forces do?
The build-up has targeted consideration on a slender set of potential missions somewhat than any type of floor marketing campaign, specialists say.
Ruben Stewart, senior fellow for land warfare on the Worldwide Institute for Strategic Research (IISS), informed Al Jazeera {that a} floor marketing campaign shouldn’t be possible at this level.
The 2003 invasion of Iraq required round 160,000 troops for a rustic that may be a quarter the dimensions of Iran, he famous, whereas the fight power at present deploying, not together with supporting troops, consists of two battalions of US Marines and two battalions of paratroopers, every of that are about 800 in quantity – a complete of round 3,600.
“The power being deployed is per discrete, time-limited operations, not a sustained floor marketing campaign. Each are rapid-response, modular forces designed for raids, seizures of key terrain, and short-duration missions with restricted follow-on presence,” Stewart stated.
He additionally famous: “What’s notably absent are the heavy armoured models, logistics depth, and command constructions required for a chronic land struggle. In sensible phrases, it is a power that may act rapidly and selectively, however not one that might maintain operations deep inside Iran or over an prolonged interval.”
Whereas no floor operation has been ordered, the size and composition of forces, mixed with public statements from US officers, recommend no less than three situations could also be into account.
These embody seizing or blockading Kharg Island, clearing Iran’s shoreline to reopen the Strait of Hormuz, and, in probably the most consequential state of affairs, securing Iran’s nuclear materials.
Kharg Island, a five-mile (8km) coral outcrop roughly 26km (16 miles) off Iran’s southwestern coast, handles an estimated 90 p.c of Iran’s oil exports. US air strikes earlier this month broken navy infrastructure there, together with its airfield.
Past Kharg, US Marine forces might perform helicopter-borne raids in opposition to Iranian missile websites, mine stockpiles and fast-attack craft alongside the Strait of Hormuz.
Of the three choices, securing the Strait of Hormuz is probably the most reasonable operational state of affairs, Stewart stated.
This could possible take the type of “restricted motion alongside the Strait of Hormuz comparable to securing key maritime terrain or suppressing threats to transport. That aligns with the capabilities of amphibious and airborne forces working from sea and regional bases,” he stated.
Seizing Kharg Island is technically possible however extra escalatory, he added, given its centrality to Iran’s oil exports. “In contrast, securing Iran’s nuclear materials could be the least reasonable with this power as it might require a far bigger, sustained floor presence,” Stewart stated.
Total, “the best escalation danger comes from strikes on strategic infrastructure like Kharg Island or nuclear websites, which might possible set off a broader Iranian response,” he stated. “Extra broadly, as extra US forces are drawn into the Center East, there’s a danger that different actors exploit decreased US presence or consideration elsewhere, so escalation dynamics should be assessed globally, not simply throughout the rapid theatre.”
Rubio’s remarks about securing nuclear materials have additionally raised the prospect of operations concentrating on Iran’s key amenities, together with Natanz, Fordow, and the Isfahan Nuclear Expertise Centre. These websites have already been struck from the air.
Retired Admiral James Stavridis, former NATO supreme allied commander, warned in a latest Bloomberg opinion piece that any assault on Kharg Island would face “large drone assaults, small boats loaded with explosives, and missiles” throughout transit by means of the strait.
He added that Iranian forces on the island could possibly be “simply overcome by the primary waves of US forces”, however cautioned that it could possibly be closely booby-trapped.
Diplomacy alongside escalation
The navy build-up is unfolding alongside a fragmented and unsure diplomatic effort and is greatest understood as “coercive leverage somewhat than a choice for struggle”, Stewart stated.
“By shifting forces into theatre, the US is growing its bargaining energy, signalling that it has choices if diplomacy fails.”
Stewart warned, nonetheless, that it is a delicate balancing act. “As power ranges develop, notably in the event that they increase past rapid-response models into heavier, sustained formations, the political and operational momentum turns into tougher to reverse. At current, the deployment stays beneath that threshold, however continued build-up would enhance the danger of inadvertent escalation or decreased diplomatic flexibility.”
On March 24, Trump stated the US and Iran had reached 15 factors of settlement in talks aimed toward ending the battle, describing discussions as “very, very robust”.
Iran, nonetheless, has denied any direct negotiations. Overseas Ministry spokesman Esmaeil Baghaei stated Tehran had obtained messages from “sure pleasant states conveying the US request for negotiations to finish the struggle”, including that “acceptable responses got.”
Final weekend, Trump issued a 48-hour ultimatum for Iran to reopen the Strait of Hormuz or face strikes on its energy vegetation. Hours earlier than the deadline expired, he introduced a five-day extension, citing “productive” conversations.
On the centre of rising diplomatic efforts is Pakistan, which has moved to place itself as a possible middleman.
Pakistan’s military chief, Subject Marshal Asim Munir, spoke to Trump on Sunday, whereas Prime Minister Shehbaz Sharif held talks with Iranian President Masoud Pezeshkian on Monday, stressing the necessity for de-escalation.
Sharif later made the provide public in a put up on X on March 24, tagging Trump, US envoy Steve Witkoff and Iranian Overseas Minister Abbas Araghchi.
“Topic to concurrence by the US and Iran, Pakistan stands prepared and honoured to be the host to facilitate significant and conclusive talks for a complete settlement of the continuing battle,” he wrote.
Trump reposted Sharif’s assertion on Reality Social hours later.
