Writing a scene where the general of a fantasy medieval-style army is talking to the troops about the upcoming battle and I've used the phrase "engage the enemy" several times. What's another way to speak of the clash of the two sides? Specific example: “Junior and Senior Riders, go ahead and report to your company. Initiates, stay here out of the way until the main body has engaged the enemy. Then rescue the wounded when you can. Do not directly engage with the enemy.” The general is telling the noobs to stay put until the main body first clashes with the bad guy army. Then to dart in and rescue the wounded without getting into any fights with the bad guy army. Ideas on a way to say this without recycling the same phrase, but while still sounding all formal and military-ish?
