M136 (AT4) w/o rocket trail...possible?

[SEAL84]

Is there any way to make an antitank weapon in OFP with a non-rocket powered projectile?

I noticed that a new M136 addon has a rocket trail behind it, and I remembered right then that the US M136 (AT4) weapon is unpowered in-flight.

I've seen footage of a soldier firing one, and it just made a big THUMP sound and this little bomb goes flying out towards a target tank...there was no smoke trail, if I remember right.  

Is this possible, or does OFP assume that all AT weps are rocket-powered?  If not, somebody please make one

turn the rocket into a mortar.  some guy did it to kegetys rpg-7.

the arc is also MUCH more realistic, as it arcs.  problem, is, i dont think it will guide onto the target

it also doesnt give off light during night, but, m136 rounds dont give off light in real life.
