Section 166 punishes abetting what the accused knows to be an act of insubordination by an officer, soldier, sailor or airman in the Army, Navy or Air Force of the Government of India, where the act of insubordination is committed in consequence of that abetment, with imprisonment up to two years, or fine, or both.
Verified against the National Crime Records Bureau's official BNS–IPC concordance (Sankalan Portal), which maps Section 166 to old IPC Section 138, and cross-checked directly against the bare text of both Acts.
| BNS section | IPC, 1860 equivalent | Category |
|---|---|---|
| 166 | 138 | Substantively changed |
Substantively changed: Old IPC Section 138 capped imprisonment at "six months." Section 166 raises this cap to "two years." The remainder of the provision is otherwise identical. (A separate old IPC provision, Section 138A, dealing with the application of certain sections to the Indian Marine Service, was already repealed in 1934 and has no bearing on this comparison.)
Whoever abets what he knows to be an act of insubordination by an officer, soldier, sailor or airman, in the Army, Navy or Air Force, of the Government of India, shall, if such act of insubordination be committed in consequence of that abetment, be punished with imprisonment of either description for a term which may extend to two years, or with fine, or with both.

This section requires that the accused know the conduct being abetted is an act of insubordination, and that the act of insubordination is actually committed as a consequence of that abetment. Unlike the assault-related provisions elsewhere in this Chapter, there is no separate lesser offence for mere abetment without the act being carried out; this section is conditioned on the insubordination actually occurring.
Yes. The section applies where the act of insubordination is committed in consequence of the abetment; unlike some other provisions in this Chapter, it does not separately punish mere abetment where the act never happens.
Yes. The section specifically requires that the accused abet what he knows to be an act of insubordination.
Old IPC Section 138 capped imprisonment at six months. Section 166 raises the maximum to two years.
