Marine Corps SkillBridge.
The Marine Corps tightened SkillBridge harder than any other service in 2024, citing unit-readiness drain. MARADMIN 280/24 (effective 31 Aug 2024) reintroduced a tiered category system; NAVMC 1700.2B (April 2025) is the current standing reference. E5 and below get up to 120 days; SNCOs, warrant officers, and officers cap at 90. Category III participation requires a General Officer and cannot result in a gapped billet.

Why the 2024 tightening matters
The June 2024 Marine Corps decision to compress SkillBridge — covered widely in defense press — was driven explicitly by unit-readiness concerns. The Marine Corps stated SkillBridge participation at unrestricted levels was creating manning gaps in deployable units. The result is a service that grants SkillBridge less generously than DoDI 1322.29 allows and routes higher-tier requests through general officers. If you're an SNCO or officer planning to use the full 180 days, plan early and coordinate with your chain on backfill before you submit.
