Two reservists who died in the Brecon Beacons were taking part in the selection process for the Territorial SAS, the BBC understands.
The two soldiers were on a training exercise on the hottest day of the year in Powys on Saturday.
A third is in a serious condition after Saturday's incident which is thought to involve six soldiers collapsing in hot weather.
The Ministry of Defence (MoD) refused to comment on reports.
Cafe owner Denise Morris told the BBC's Hywel Griffith what she saw.
