As a less intentional version of this - at early stages of the 1973 war, Israeli forces in certain areas tended to consist of whatever scraps of forces arrived at the front first. This led Egyptian and Syrian intelligence to wildly overestimate Israeli force sizes, since they would sometimes see the identifying marks of multiple brigades when facing a very small force.
