What abbreviation represents a Second Lieutenant in the Army?

The abbreviation for a Second Lieutenant in the Army is "2LT." This designation is commonly used in military communications and documentation to refer to this specific rank. The "2" indicates that the individual holds the rank of Second Lieutenant, while "LT" stands for Lieutenant. This abbreviation is standardized and recognizable within military contexts, ensuring clarity and consistency across various forms of official communication.

Other abbreviations such as "SLT," "LT2," and "2LTN" do not accurately represent the rank of Second Lieutenant.
