Qatari and US paratroopers held a joint training exercise in Doha on Tuesday which American officials said reinforced "the enduring military-to-military" partnership between the two countries.
The "Friendship Jump" comes at a time when a boycott of Qatar by a Saudi-led bloc has entered its third month.
More than 40 paratroopers took part in the routine exercise, jumping from a C-130 transport aircraft, according to a statement from the US Special Operations Command Control.
The training "is indicative of the strong relationship between our two countries", said Colonel David Keesy, senior defence official for the US Embassy in Qatar.
"This is part of a multi-spectrum, training evolution that is indicative of the mil-to-mil relationships and partnership and cooperation between the US and Qatari militaries."
Tuesday's US-Qatari military exercise is the second since the onset of the Gulf crisis, following naval exercises in June.
