Candidate passages:
The Royal Iraqi Air Force (RoIAF) had been trained and equipped by the British prior to independence in 1932.
One result of this was the dominance of British-built aircraft in the RoIAF inventory.
In 1941, the sole RoIAF single-purpose fighter squadron, No.
4 Squadron consisted of seven operational Gloster Gladiators at Rashid Air Base.
After a pre-emptive RAF attack from RAF Habbaniya against blockading Iraqi forces, Iraqi Gladiators took part in attacks on the British air base, strafing it ineffectively on 2 May.
Although much of the RoIAF was destroyed in the air or on the ground in the following days, the Iraqi Gladiators kept flying until the end of the war, carrying out strafing attacks on A Company of 1 Battalion The Essex Regiment on the outskirts of Baghdad on 30 May.
Before the outbreak of hostilities in Iraq, the 4th Service Training School at RAF Habbaniya operated three old Gladiators as officers' runabouts.
With the increased tension, the base was reinforced with another six Gladiators on 19 April, flying in from Egypt.
During the early part of the war the nine Gladiators flew numerous sorties against air and ground targets, taking off from the base' polo field.
The Gladiator force in Iraq was further reinforced when, on 11 May, another five aircraft arrived, this time from 94 Squadron in Ismaïlia on the Suez Canal.
A last resupply of Gladiators came on 17 May in the form of four more 94 Squadron machines.
During the fighting, the sole Gladiator-on-Gladiator kill occurred on 5 May, when Plt.
Off.
Watson of the Fighter Flight shot down an Iraqi Gladiator over Baqubah during a bomber escort mission.
The Iraqi Gladiators' only claim during the war was a Vickers Wellington bomber shared with ground fire on 4 May.
Immediately after launching his coup against King Faisal II in early April 1941, Prime Minister Rashid Ali al-Gaylani approached Germany and Italy for help in repelling any British counter-measures.
In response, the Germans assembled a Luftwaffe task force under Iraqi colours called "Fliegerführer Irak" ("Flyer Command Iraq") which from 14 May operated out of Mosul.
Before this force collapsed due to lack of supplies, replacements, quality fuel and aggressive RAF attacks, two Gladiators fought a pair of Bf.
110s over Rashid Airfield at Baghdad on 17 May.
Both German machines were swiftly shot down.
"Regia Aeronautica" sent 12 Fiat CR.42s that arrived in Iraq on 23 May.
Six days later, the Fiat CR.42s intercepted RAF Hawker Audax and clashed with escorting Gladiators in what was to prove the final air-to-air air combat of the brief campaign.
Italian pilots claimed two No.94 Sqn Gladiators but one Fiat was shot down by a Gladiator flown by Wg Cdr Wightman, close to Khan Nuqta.
The Iraqis continued to use Gladiators until 1949 for ground attack missions against the Kurds. 
The Pittsburgh Gladiators season was the second season for the Arena Football League franchise. 
The Pittsburgh Gladiators season was the third season for the Arena Football League franchise. 
There were many different types of gladiator in ancient Rome.
Some of the first gladiators had been prisoners-of-war, and so some of the earliest types of gladiators, Gauls, Samnites, and "Thraeces" (Thracians) used their native weapons and armor.
Different gladiators specialized in different weapons, and it was usual to pair off combatants with widely different, but more or less equivalent, equipment.
As a rule gladiators only fought others from within the same school or troupe but sometimes specific gladiators could be requested to fight one from another troupe.
Forensic studies have shown that as a rule gladiators fought to strict rules and barefooted.
Elite gladiators wore specially made armour for the pre-game parade "(Pompa)".
Julius Caesar's gladiators wore solid silver armour, Domitian's wore solid gold and Nero's wore armour decorated with carved amber.
Peacock feathers were used for plumes while tunics and loincloths had patterns in gold thread.
The gladiators changed into their combat armour for the actual fights although even the simplest were elaborately decorated.
Reliefs and mosaics often show gladiators with various numbers of tassles hanging from one arm or leg.
The reason for their use is unknown and historians speculate that they may have served as a "scorecard", indicating the number of fights a gladiator had won.
During combat, musicians performed accompaniment that altered tempo to match that of the combat.
Typical instruments were a long straight trumpet "(tuba)", a large curved brass instrument called the "lituus", and a water organ "(organum)".
During the Imperial period, the games might be preceded by the form of musical-comedy variety show known as "mimus", with the performers sometimes costumed as animals.
An image from Pompeii shows two figures labeled "flute playing bear" "(Ursus tibicen)" and "horn-blowing chicken" "(Pullus cornicen)", who may have been part of such a "mimus". 
The Colosseum and its activities supported a substantial industry in the area.
In addition to the amphitheatre itself, many other buildings nearby were linked to the games.
Immediately to the east is the remains of the "Ludus Magnus", a training school for gladiators.
This was connected to the Colosseum by an underground passage, to allow easy access for the gladiators.
The "Ludus Magnus" had its own miniature training arena, which was itself a popular attraction for Roman spectators.
Other training schools were in the same area, including the "Ludus Matutinus" (Morning School), where fighters of animals were trained, plus the Dacian and Gallic Schools.
Also nearby were the "Armamentarium", comprising an armory to store weapons; the "Summum Choragium", where machinery was stored; the "Sanitarium", which had facilities to treat wounded gladiators; and the "Spoliarium", where bodies of dead gladiators were stripped of their armor and disposed of.
Around the perimeter of the Colosseum, at a distance of 18 m (59 ft) from the perimeter, was a series of tall stone posts, with five remaining on the eastern side.
Various explanations have been advanced for their presence; they may have been a religious boundary, or an outer boundary for ticket checks, or an anchor for the "velarium" or awning.
Right next to the Colosseum is also the Arch of Constantine.
