One of the things my son felt was most useful was a good quality electric razor. He initially did not plan to buy/bring an electric razor, but I was worried about him having to take the time to shave so I bought him a nice braun electric shaver and he has been so glad to have it. He grows a heavy beard quickly and during basic needed to do a quick shave twice a day to keep the shadow at bay. This was such a great time saver for him.
