Hi Denise,There was at that time 3 rifle companies and 1 heavy weapons company in each battalion. Here are the breakdowns. The 1st battalion consisted of Companies A,B,C which were rifle companies and D company was a heavy weapons company. Thhe 2nd battalion consisted of Companies E,F,G, which were rifle companies and H company was heavy weapons company. The 3rd battalion consisted of I,K,L which were rifle companies and M company was a heavy weapons company. I am a retired Sargent Major with 30 yrs service and my first assignment when I was 17 yrs old was with "K" Company, 187th Airborne Regimental Combat Team. One of those crazy paratroopers.Hope this helps you understand how the battalion were back then----it's all different now.
