Can you be a RAF sniper?

Yes however they tend to use explosive rounds

All snipers may use explosive rounds - depending on the targets!

The RAF Regt has snipers - they do exactly the same selection & training courses as British Army snipers.

Answer:

Explosive rounds?

No.

The RAF Regiment uses the Accuracy International L115A1 rifle chambered for .338 Lapua Magnum rounds. These rounds are NOT explosive.
