Melinda May is a level 7 S.H.I.E.L.D. operative, nicknamed "The Cavalry". A veteran pilot and soldier with years of experience, she withdrew from field duty after an incident in Bahrain which left her slightly damaged. However, she returned to the field when Agent Phil Coulson recruited her onto his team.
- "May used to be different. She was always quiet, she was just... she was warm. Fearless in a different way. Getting in trouble, pulling pranks, thought rules were meant to be broken.""
- ―Phil Coulson
Trained by the best S.H.I.E.L.D. has to offer, she became an ace pilot and a weapons expert, a soldier who can perform above and beyond the call of duty. She's one of the few S.H.I.E.L.D. agents who have more black belts than the notorious Natasha Romanoff.
During her career, she met Agent Phil Coulson, one of the highest-ranking S.H.I.E.L.D. agents and the right-hand man of Director Nick Fury. Coulson would describe May as warm, fearless and not afraid to break rules. May was quiet, but not above pulling pranks on her fellow agents. 
May and Coulson would often talk of being able pick their own operations and call their own shots without the bureaucracy and red tape.
- "Forgot I was working with 'The Cavalry'."
"Don't ever call me that."
- ―Grant Ward and Melinda May
At one point, May, Coulson and a team of agents were dispatched on an "Index Asset Evaluation and Intake" (or "Welcome Wagon") mission, investigating a newly discovered powered individual to Manama, Bahrain, that went south.
When a civilian girl and several S.H.I.E.L.D. agents were being held by the followers (or worshippers) of the "Gifted" individual they had come to investigate, May took it upon herself to solve the problem. May went in by herself without a weapon and "crossed off" the enemy force, rescuing the agents. The incident earned May the nick-name "The Cavalry" within S.H.I.E.L.D., a designation she despises.
May has never spoken of what happened during the incident, but it changed her. The warm, rule-bending nature of her personality seemed to be gone, despite Coulson's efforts to draw it back out. May withdrew from combat duty, retreating to a desk-bound administrative position within the S.H.I.E.L.D. bureaucracy.
Back in the FieldEdit
- "You guys talk too much."
- ―Melinda May
However, after the battle of New York, May was approached by Nick Fury himself and ordered to be his eyes and ears on the newly resurrected Phil Coulson. May's orders were to report to him directly if Coulson showed any side-effects or dangerous behavior after his treatment with the alien GH.325 drug. Fury believed that given their shared history, Coulson would recruit her for his new team. To aid in her mission, she put together a team of agents that may be necessary to treat or act on Coulson. Coulson was then given specific mission parameters and was maneuvered into picking May's choices.
As expected, Phil Coulson came to the office where she worked and asked her to join his team. Still haunted by her past experiences in the field, she was genuinely reluctant to return to combat, but she agreed when Coulson told her that he just needs her to "drive the Bus." 
However, field work is not always a stable environment. May was angered after seeing inadvertent combat in Peru, but her skills helped save her team and re-take the Bus from Camilla Reyes's hijackers. 
During the action in Malta, May initially assumed that she would be on the strike team to rescue Dr. Franklin Hall, to her dismay. When Coulson informed her that he was going in with Ward instead, May expressed doubt, stating that field work and specialist work were two different things.
During the operation, May was frustrated at being stuck at the backend of the op, where she couldn't do anything to help her team. Upon Coulson's return, May informed him that she would report the next time combat duty came up. 
- "You told me that you were ready for combat. That you had my back."
"Don't ever doubt it."
- ―Phil Coulson and Melinda May
May returned to combat duty without hesitation. She acted swiftly (and without authorization) to apprehend renegade S.H.I.E.L.D. agent and Coulson protégé, Akela Amador before she could complete her mission in Belarus. 
In Hong Kong, she participated in the attempted rescue of Index listed pyrokinetic Chan Ho Yin from his captors in the Centipede Project. When Chan started to use his powers against the S.H.I.E.L.D. team, killing Agent Kwan Chen, May injected Chan with an overdose of the Centipede formula, causing an explosive overdose. 
She lived up to her nickname of "The Cavalry" when Agents Grant Ward and Leo Fitz were stranded in the middle of a hot operation without an extraction plan along the South Ossetian border. She piloted the Bus without authorization into an active hot spot where she and her team rescued their team-mates.
In Ireland, she took up the strength-enhancing Berserker Staff in combat against the members of a Norse Paganist hate group. She was able to control the rage-inducing properties of the staff, and claimed it was because she lived with her rage every day.
