A word on Air Cav

what use is the valkyrie and vendetta other than popping tanks and generally being hard for the enemy to kill? its a transport, but a half assed one. In order to have true air cavalry you would need a lot of things. and before I delve into the list of all the stuff that would be necessary lets take a look at what makes Air Cav decent... despite the incredible cost :(

So what exactly is Air Cavalry? flying horses? basically its when all your troops, generally light infantry, have a very mobile helicopter, or in this case a valkyrie. Typically the major advantage to this is real warfare, is that you can get to important places quickly, and well ahead of the enemy. However in Warhammer 40k, we don't have to worry about moving the troops around, because we are all gentlemen and totally shake hands that we will stand in massive lines and whatnot. So what advantage is mobility to a guard army in 40k? not a whole lot... if you wanna run this, its probably best you rely mainly on the power of your valks and vendettas. However, if you run vets with demolition charges, meltaguns, shotguns, and you have Harker and Bastonne as well as stocking up on one Colonel Straken, you don't have a plan that will necessarily suck. and you get the fun of fielding a badass air cavalry unit. Not to mention, you would have a lot of flexibility, and it would come in very handy in an apocalypse game, where you can just zip around securing objectives where necessary.

Really, there is a decent strategy against any type of army. your opponent relies heavily on tanks? zip over or deep strike disembark lads and pop em with meltaguns. Fighting an assault heavy army? take out their big guns and then shoot them from a distance playing the Tau game of fire and retreat. Fighting an army relying on a gunline? fly up there blast em with the valks, and hit em with the shotguns and meltas.

All in all, its probably not the best kind of army to run with. Not to mention you won't have a lot on the table, and your men will still be regular guardsmen with crappy 5+ saves, and toughness 3. and the biggest kicker for me is, in order to do this you would need like 8 valkyries, which clocks in at $500. HOWEVER. your men will die with incredible style, and people will be jealous of how cool your Vietnam War themed army is... not recommended, but doable and loved by dog faced soldiers everywhere.
