LOL, no, not for this (the older models looks also worse, this is a second version
)
This is a PIAT from British army, used in the world war ..... anti-tank, it shoot HE half-rocket grenades (a mix from an RPG and a mortar propeller system), and fire it with an enormous spring that is in the main body, the spring do both giving a "push", and igniting the launch charge, and was supposed that the initial blowback of the launch charge was rearming the spring.
But, first, half of the times, the spring was not rearmed, and it need the strenght of TWO MEN for reload it manually (easy to do, when all around are shooting you
) ..... second, the recoil was absurd ..... third, it was originally designed for a single-man use, but the complications and the weight was constraining to use 2 mens for act it .....
And, last but not least, sometimes the launch charge was not igniting, but the spring hit was still enough for throw the HE grenade a pair of meters out from the holder ..... and what you think can happen, to the users, when a HE grenade capable to blow-up a tank, instead blow up in front of you ? (KABOOM, no more PIAT and users
)
For this i call it a fail
