Military presses are a excellent compound exercise hitting the front (anterior) delts, laterial delts, upper pecs, triceps & traps for the most part. If you hold the grip a little narrower, about shoulder width, the front delts and triceps will get the brunt of the workload. It is a prime shoulder mass builder.
If your into heavy bench/incline/dip work than you should be getting more than enought anterior delt involvement. If you still want to add versions of the front raise than you might try BB raises or alternating standing DB raises, knuckles up all the way. Do not use a hammer grip. Lying on a incline and doing front raises is favorable (can ever reverse your position by lying face down and do raises that way). Let the DB's hang all the way down, as a starting point, and bring them up to almost top position overhead when lying in the usuall face up position.
Side Bar: the original military press was done with the heels together, back ramrod straight the the head not moving at all throughout the press. Hence the name Military Press. Good Luck.
