It's not known where they're heading. They could be en route to Afghanistan. The Harrier squadron stationed at Britain's Camp Bastion suffered heavy mid-September losses. Another Harrier unit replaced it.
Perhaps the newly deployed squadron has another mission. It's also possible that "the F/A-18s are heading to the Gulf Cooperation Council region."
"A number of air superiority squadrons, including an F-22 Raptor squadron, have already deployed to the region. If that is the case, the squadron is intended simply as reinforcements or replacements for assets currently deployed there."
In late September, it was learned that hundreds of US forces and security personnel will remain in Iraq despite no congressional funding for them.
Others may join them. Authorization for US troops to train and assist Iraqi security forces expired on September 30. According to Pentagon spokesman Lt. Col. Wesley Miller:
"No personnel will return immediately to the United States on October 1, 2012 while DoD is reviewing the effect of not being authorized under the Continuing Resolution to continue the training of Iraqi Security Forces (ISF) following expiration of the Iraqi Security Forces Fund (ISFF) authority on Sept. 30, 2012."
America's Iraq war never ended. Obama's claim otherwise was false. Stratfor reported that US General Robert Caslen said Army special forces were sent to Iraq to advise on counterterrorism and intelligence related matters.
Perhaps MC-130 aircraft transported them there. In late September, Le Figaro said 100 French special operations troops were sent to sub-Saharan Africa to engage northern Mali militants.
"Le Figaro also reported that maritime patrol aircraft that can be used to collect intelligence will be deployed to the region and that commandos of the French navy will reinforce the French special operations troops."
In September, Italian journalist Guido Olimpio said US unmanned aerial vehicles (UAVs) currently track Cyrenaica-based militants. It's eastern Libya's historical name.
