The Launch Pad's scale model of the USSR's GRAIL SA-7.

This shoulder-fired infantry missile was originally very similar to the U.S. Army's Redeye missile. It had the advantage of being lightweight and portable, but was handicapped in that it was effective only against very small aircraft or helicopters. This, plus an inability to lock onto any heat source other than the exhaust nozzle of a departing aircraft meant that, by the time Grail was able to sight onto the attacker, there was a very good chance that its operator had already been killed! In the Yom Kippur war almost half the A-4 aircraft hit by Grail missiles were able to return to base. Range is listed as 10km, speed is about Mach 1.5, and it carries a warhead weighing 5.5 lbs.
