Is 'active service' the same as 'active duty'?

Yes, in modern military contexts, especially American English, 'active duty' is a direct and very common synonym. 'Active service' is slightly more formal and common in UK historical contexts.

Can you use 'active service' for non-military jobs?

It is very rare and would be a metaphorical extension (e.g., 'This old printer is still in active service'). In most cases, use 'actively working' or 'in service' instead.

What is the opposite of 'on active service'?

For military personnel, the opposite could be 'in the reserves', 'on inactive status', or 'discharged'. For equipment, 'out of service', 'decommissioned', or 'in storage'.

Does 'active service' always mean seeing combat?

Not necessarily. It means being in a state of full-time military duty during a period of conflict or operational readiness. A soldier on active service might be in a support role away from direct combat.
