According to several sites dealing with this matter, there were no BARs assigned to these battalions.
But in several accounts, like the one below, BAR gunners are being mentioned;
The next morning tank-infantry teams were formed and the 68th entered Rittershoffen. Lt. Gosselin, platoon leader, 3rd platoon C-68, told PFC Harry Kemp he needed more fire power in the platoon. He gave Harry a Browning Automatic Rifle and appointed two men in the platoon to be Harry's ammunition bearers.
14th Armored Division
Any information on how many and when BARs were assigned to Armored Infantry units is therefore welcome.
Thanks in advance.
