Medikit and secondary weapon right off the training, that's not a good idea. Start off with just bare minimum, maybe just drop the medikit (2 kg), and maybe spare mag for pistol or if you want to keep medikit, don't give him pistol yet. I found that I never use them anyway, at ranges they're remotely useful it's better to lob a flashbang followed by frag grenade. If you select your recruits well (I recommend taking only 30+ mind, 20+ accy and speed, 35+ strength, 20+ assault or sniper skill), they'll quickly gain enough strength to carry whole load (around 20 missions max to get over 40 strength). I do this: choose just the recruits that fit these criteria and add some fodder to fill whole team, and gradually month by month I replace fodder with better recruits. Losses of fodder are irrelevant.
