No- they don't let us keep them. Would be nice, but the Army will reissue your rifle to another soldier, or store it until it is needed.
If you mean the US Army, the M16 and the M4 variant of the M16.
M16 series
Not entirely. The Marines retained the M16, and most Army mech units opted for the M16A4 rather than the M4.
The M16 was first used by the United States Air Force in 1962. Prior to this it was known as the AR-15. The United States Army began to field the M16 in 1965 in Vietnam.
The M14 was up to about 1965. After that, the M16
The M16 is the US Army's choice of assault rifle since 1964, however, as early as 1960 its prototype, the XM16E1, was seen on the frontlines.

It is a yearly qualification that is added to you're record for promotional points.
During a time which the US military was fielding a .30 weapon (M14 rifle), jungle warfare required a weapon that was lighter and could "put the lead out." The M16 could do this. Consequently, the M16 was sent to Vietnam as a jungle rifle; all other US forces (army, marines, navy, air force was the only exception) retained their M14 rifles around the world. ONLY troops in Vietnam received the jungle rifle (M16). Until after 1970...then the M16 began to replace the M14s.
A M16 cost about $2000.00
Because an army can do alot more damage and bring alot more food home than a soldier.
