The uniformed operative known only as "Number Four" was a member of the Sanitation Unit, which tried to break Captain America out of jail as part of a plot to frame Cap for murder, coerce him to flee from the law, and further discredit his reputation.
Although another Sanitation Unit agent was known as "Number One," it was Number Four who led the unit.
"Number Four" was referred to by name (or, number, really) in panel 6 on page 3 in Captain America (vol. 1) #171.
Another Sanitation Agent said: "Our uniforms and nose filters protected us--just as you said, Number Four!"
Then Number Four replied: "Of course. Now let's get Cap out of here--pronto!"
The Sanitation Unit is able to use a sleep gas to subdue Captain America. Later, Cap regains consciousness, but pretends to still be unconscious while he listens to the Sanitation Unit agents talk.
Number One said: "...Penn street doesn't want any errors!"
Another Sanitation Unit agent said: "Right, Number One! But ain't it a laugh, though-- --when Cap wakes up, he's gonna find himself even more discredited-- --never knowing we are actually working against him!"
Then Number Four said: "Let's laugh later, Number Eight--after we've made our 'anonymous phone call' to the cops-- --and then to the news media!"
Captain America has just regained consciousness. He says: "Save your dime, Jack! That call's gonna be delayed!"
Number Four is surprised, and says: "Impossible! Nobody recovers from that gas so qui--"
Then Cap punches Number Four.
A surprised agent exclaims: "He's knocked out Number Four!"
Captain America subdued or knocked out the other agents of the Sanitation Unit. Then Number Four regained consciousness (panel 5 on page 4) and attempted to flee.
In panel 1 on page 6, Captain America spots Number Four and thinks: "Their leader--'Number Four'--appears to be up and about--and showing a high tail-- a profile which needs some distinct lowering!"
Captain America knocks Number Four down with his versatile shield. He grabs Number Four and threatens the cowering man convincingly, saying: "Okay, Number Zero--I hear something about 'Penn Street!' Either you give me some facts-- --or you're getting a one-way flight to Tucson-- without an airplane! Read me?"
Number Four starts to tell Cap the actual address of the boss he was reporting to. He manages to murmur "...S-seventeen... oh..." before fainting.
Captain America observed: "Blast! He was so panicked, he passed out! I forget that sometimes these goons think I mean those threat!"
As seen in panel 4 on page 16, the actual address of the place Cap was looking for was 1701 Penn Street, so Number Four was attempting to provide legitimate information before he passed out due to his fright.
