Ranks Comparison

| Group Captain | Colonel | Captain |

⚠️ COMMON TRAP
Navy "Captain" ≠ Army "Captain" — Navy Captain = Army Colonel rank equivalent. Don't confuse ranks across services. Also: IAF has
no Field Marshal equivalent permanently; "Marshal of the Air Force" is honorary only.

🎯 JAN 2026 AFCAT PYQ — HISTORY
Rowlatt Act (1919) — authorized British to arrest & imprison any Indian WITHOUT trial. The Satyagraha against it was called in
April 1919 (NOT 1917 — that was Champaran). Only Statement 1 of the PYQ was correct.
Battle of Stalingrad = World War II (1942–43) — decisive Soviet victory against Nazi Germany. A trap option was Russian Revolution.
