Army chiefs face the nightmare prospect of having to consider their soldiers' childcare problems before giving them orders. The devastating blow follows a successful sex discrimination claim brought by a single mother. Tilern DeBique, 28, says she was forced to leave the Army because she was expected to be available for duty around the clock. She was formally disciplined when she failed to appear on parade because she had to look after her daughter. She was told the Army was a 'war-fighting machine' and 'unsuitable for a single mother who couldn't sort out her childcare arrangements'.
