“spray oven cleaner makes a pretty fair substitute.”
Also, oven cleaner spray, bug spray cans that shoot a long distance are a backup but the spray gun with red laser is superior to any substitute, but long distance spray oven/bug cans could be left out all the time and put in obvious places they night be needed.
What I’m saying, is, MORE is better, have them all easily available.
This is the mindset the Israelis have about antitank weapons for their infantry. Yep, they've got outstanding tank crews, trained to the level of Olympic athletic competitors, and antitank guided missile crews that figure to pick up any strays the tankists miss.
But they know that no plan survives contact with the enemy, so each squad has an M300 antitank *bazooka* and often a couple of captured enemy RPG launchers; they've captured quite a few, in '56 and '67, '73 and '82,'92 and '96 in Lebanon and Gaza on '08,'12 and last year. So they can kill bad guy tanks, especially in the dark, up close as well.
But they do not leave it at that: they also issue the Light Antitank Weapon, and the East Bloc counterpart, the Flea [Mukha to individual riflemen, and still issue antitank rifle grenades for the launchers on the end of every Israeli M16, Galil and now the new Tavor bullpup rifle. There's even a AT grenade launcher made that screws onto the end of the old Uzi submachinegun, now mostly out of service but still around in a few police reserve and kibbutz armories. And of course the Israeli grunts are equally at home with the foot soldier's field expedients: .50 caliber ammo cans filled with C4 and fitted with a hand grenade fuze, and even the circa 1939 Finnish *Molotov Cocktail,* though they are far less effective against tanks in this day of Diesel engines.
But the point is, the Israeli grunts do not put all their antitank eggs in one basket. And as you observe, neither should we when dealing with the threats more likely to come our way in our homes...for now.
