Both M13 and M16 have only one weapon system making long range shots easier to hit with all weapons. They also carry plenty of ammo (both 4800 rounds or 12 / 6 reloads) and will fire long after the M15 ran out of 37 mm and 12.7 mm rounds. Of course, the Combination Gun Motor Carriage has some advantages to the machine gun only armed versions: A nasty cannon and actual armour, the M15A1 is entrusted with the ability to engage at a longer distance down aircraft faster, and most importantly, survive much longer. However, the price paid is the inability for the armament to cover the vehicle's front and slower turret rotation. The latter can be addressed by driving backwards while in a combat zone.

 After World War II, many M15s were given to Japan under the Military Aid Program to support their new military formation. The M15s saw service again in the Korean War as an anti-aircraft and ground support vehicle. However, the M15 was classified as "limited standard" like its M16 counterpart due to its lower efficiency against the newer planes present due to advances in technology. The M15 "Special" was taken up as an improved version of the M15 and adopted due to the larger quantity of 40 mm ammo than the 37 mm, this caused the modified M15s to be designated the T19, then officially as the M34. The M15 was declared obsolete in 1946 and retired sometime after that, with the remaining ones given to Japan.

 Following the success enjoyed by the T28E1 CGMC in North Africa, US army command decided to launch full-scale production of a self-propelled anti-aircraft weapon with mixed armament. The weapon was standardized as the M15 CGMC.

 Compared to certain other SPAAs ([[ZSU-37]], [[Wirbelwind]], [[M13 MGMC|M13]], etc.) the M15 cannot be used effectively in an anti-vehicle role. The average [[BR|battle-rating]] is too high and the penetration value of the AP shells to low. While it does have increased armour compared to earlier models, it is still not strong enough against the devastating tank HE shells. However, the armour performs well versus the average aircraft armament.
-With the 37 mm cannon the CGMC has an good tool versus [[:Category:Bombers|bombers]] and [[:Category:Strike aircraft|strike aircraft]]. The ammo is limited though. Reserve the fire for certain hits. Against fighters the same tactic should be applied, while now the 12.7 mm HMG should be used as well, their ammo is limited, too. Without firing discipline, the M15A1 ammo will run out very fast.

-Unlike many other SPAA this vehicle can continue shooting once it is reloading the big gun ([[M1A2 (37 mm)‏‎|37 mm cannon]] or the smaller calibre [[M2HB (12.7 mm)|M2 Browning]] guns). However, continued fire is not the strength of this machine. It simply lacks the ammo for it, 200 shells will earn some scores, but simply cannot compete with the constant rate of fire the German [[Sd.Kfz. 6/2]] As it has an extremely short reload time. The Axis counterpart has less armour overall, yet fire rate is 40 rounds a minute higher (~160 shells/min) and has 318 shots total instead of meagre 200. In addition, the German SPAA actually has efficient high-velocity rounds with 48 mm @ 100m (1.9 inches at 110 yards).
