Weapons of the Cold War: RPG-18
In Escalation 1985 you'll be able to take down enemy tanks and infantry with the RPG-18.
It's a fire and discard weapon; once it's fired, the tube is thrown away.
You have to be careful, however, and really mean it once you decide to use it; once the safety is off, the weapon can only be made safe by firing it. The manual suggests that the weapon is fired in the general direction of the enemy, should you regret arming it. This will be simulated in Escalation 1985, so be careful.
Here are some work in progress shots of the RPG-18:
