Earlier this year, the Army released a directive allowing beards in uniform for Sikh soldiers, despite tests showing that the M50 couldn't get a perfect seal with a beard.
Bearded soldiers would not, however, be allowed to serve in the CBRNE units that are tasked with responding to contaminant attacks.
That exception opened up the doors to re-thinking the beard question, the Army G-1 uniform policy sergeant major told Army Times in February.
In addition to further tests on current Army equipment with beards, the Army's acquisition office is looking into alternative masks that could be fielded to soldiers with beards, a spokesman told Army Times in March.
That could mean, Benoit said, tiers of gas mask depending on units — something different for CBRNE soldiers and the infantry, for example.
"Right now, we do the protection for all-encompassing threats," Benoit said. "As we really take a look at what's necessary, ... for example, there might be appropriate times where you just have a scarf protection that covers your nose, mouth, that type of thing, for more specific threats."
"Beards are something that we will continue to address, because they're not going to go away," she added.
