Familiarity (Updated)

The timeframe that Funny New Guys is set is 1967.

That sets some important points for weaponry.

It means all the "work" I did looking up Blooper stuff is still relevant and the more familiar M203 won't be on the scene yet.  The XM148 has started field trials.

It also amends my list of available rounds:

See High Tech p.143 and p.145 and SEALs in Vietnam p.33 for stats.

M397 HE-AB (1964) - 15 yard min distance.  32g Octol.  0.507 lb.

M406 HE (1961) - 15 yard min distance. 32g Comp-B. 0.503 lb.

M662 Red Star Parachute (1967) - 330 yard min distance, 40 sec, 20,000 candela, falls 7' per second. 0.47 lb.

M682 Red Smoke Canopy (1967) - 150 yd. min distance. 90 sec burn time.  Deploys under a parachute that snags in tree branches.  0.48 lb. 

M713 Red Smoke Ground Marker (1965) - 15 yd. min distance.  25 sec burn time.  0.49 lb.

M715 Green Smoke Ground Marker (1965) - 15 yd. min distance.  25 sec burn time.  0.49 lb.

M716 Yellow Smoke Ground Marker (1965) - 15 yd. min distance.  25 sec burn time.  0.49 lb.

I should also note that the date I've shown is just the earliest reference I have for the round in question.  Some of them must pre-date that because the M79 is first fielded in 1961.

Found all the in service dates! 

That makes my infantry weapons list:

M16A1 rifle (XM16E1?)
M60 machine gun
M79 grenade launcher
M1911A1 pistol (but I'm amused to change that to M4...)
M26 (lemon) and M33 (baseball) are the common fragmentation grenades.
