Rugby union has 15 players per side: eight forwards (props, hooker, locks, flankers, number 8) who contest scrums, line-outs and rucks, and seven backs (scrum-half, fly-half, centres, wings, fullback) who run, kick and handle in open play. Each position carries specialist responsibilities — props anchor the scrum while the fly-half directs tactical play.
- 8 forwards (1–8) and 7 backs (9–15)
- Forwards: scrum, line-out, breakdown
- Backs: running, kicking, handling
- 15-a-side (vs 13 in league)
In practice
Rugby union's 15 positions split into forwards (1-8, generally larger, focused on scrums, lineouts and close-range physicality) and backs (9-15, generally faster, focused on running, kicking and finishing attacking phases) — this forward/back structural divide reflects genuinely different physical and skill profiles, which is why specialist training programmes for front-row forwards look dramatically different from those for wingers or fullbacks.
